PREFACE

A score of years ago (1880–1885) I was living in the mountains of West Virginia. While riding on horseback through the dense forests of that great unfenced state, I saw on every side luxuriant growths of fungi, so inviting in color, cleanliness and flesh that it occurred to me they ought to be eaten. I remembered having read a short time before this inspiration seized me a very interesting article in the Popular Science Monthly for May, 1877, written by Mr. Julius A. Palmer, Jr., entitled “Toadstool Eating.” Hunting it up I studied it carefully, and soon found myself interested in a delightful study which was not without immediate reward. Up to this time I had been living, literally, on the fat of the land—bacon; but my studies enabled me to supplement this, the staple dish of the state, with a vegetable luxury that centuries ago graced the dinners of the Cæsars. So absorbing did the study become from gastronomic, culinary and scientific points of view, that I have continued it ever since, with thorough intellectual enjoyment and much gratification of appetite as my reward. I hope to interest students in the study as I am myself interested.

For twenty years my little friends—the toadstools—have been my constant companions. They have interested me, delighted me, fed me, and I have found much pleasure in making the public acquainted with their habits, structure, lusciousness and food value.

My researches have been confined to the species large enough to appease the appetite of a hungry naturalist if found in reasonable quantity; and my work has been devoted to segregating the edible and innocuous from the tough, undesirable and poisonous kinds. To accomplish this, because of the persistent inaccuracy of the books upon the subject, it was necessary to personally test the edible qualities of hundreds of species about which mycologists have either written nothing or have followed one another in giving erroneous information. While often wishing I had not undertaken the work because of the unpleasant results from personally testing fungi which proved to be poisonous, my reward has been generous in the discovery of many delicacies among the more than seven hundred edible varieties I have found.

For ten years I have planned to publish in book form what I know about toadstools; each effort to compile my information has shown me how much more I ought to know before going into print. Even now my work is still unfinished.

I am urged by my many toadstool friends (as I lovingly call those who, from all over the land, send me specimens for identification, and grow interested with me in the work), to publish what I already know upon the subject, that they, and others, may have a helpful book to guide them to a goodly portion of the edible species, and away from those that are inedible or poisonous.

In this book I comply with these requests. I have selected over seven hundred of the most plentiful and best varieties for the table, from my toadstool bill of fare; and I describe and caution against several species, some of which are deadly in their effects, if eaten; others of which induce ill-effects more or less serious. One thousand species and varieties are named and described.

Birds, flowers, insects, stones delight the observant. Why not toadstools? A tramp after them is absorbing, study of them interesting, and eating of them health-giving and supremely satisfying.

Charles McIlvaine.

INTRODUCTION

America is without a text-book of the American species of Fungi, among which the edible and poisonous varieties are found. Many excellent but expensive foreign volumes describe species common to both continents, and several special but widely scattered monographs have been published here. The need of the mycologist, mycophagist and amateur toadstool student is a book giving the genus, names and descriptions of the prominent American toadstools whose edibility has been tested, or whose poisonous qualities have been discovered. The absence of such a book, and the universal and rapidly-growing interest all over the United States in edible fungi, have led to the publication of the present work, which includes every species known to be esculent in North America. As a precautionary measure, full explications of all those known or suspected to be poisonous are included.

Many species found in this country only have been described and named by various authors, from the time of Schweinitz (1822) to the present day. These have been published in the botanical magazines and in the papers of scientific societies and colleges. The greater number have as author Professor Charles H. Peck, New York State Botanist, who has contributed an annual report each year from 1868. These appear in the reports of the State Museum of New York, and coming from the pen of our ablest mycologist are of great value to everyone interested in the study. The classifications and (in many instances) modified descriptions by such an eminent authority upon fungoid growth should therefore be the guides to American forms, that the confusion created by numerous descriptions of the same fungus by different observers may be avoided.

Professor N.L. Britton, editor of the Torrey Botanical Club, has courteously given permission to use the descriptions of new species given in its instructive Bulletins.

Professor A.P. Morgan and Laura V. Morgan, with equal courtesy, grant the use of text and illustrations contained in the most complete monograph published upon the Lycoperdaceæ (puff-balls, etc.) of America.

While the scientific classifications and descriptions have been strictly followed, the language has been simplified—with no sacrifice of scientific accuracy—that this volume may be fully adapted to popular use.

Professor Peck has given his valuable assistance in the identification of many species, all that were difficult or obscure having been submitted to him, and the writer is deeply indebted to him for many and long-continued courtesies, aiding in study and in the preparation of this work.

Several new species have been found by the writer, the greater part of excellent food value. He preferred that these should be named, described and placed in their proper genus and section by Professor Peck, believing it to be best for the discoverers of new species to defer to one whose vast experience enables him to name and classify in accordance with the demands of American species.

Where a species is vouched for as edible, it has been personally tested by the author and his willing undertasters up to eating full meals of it, or at least beyond all doubt as to its safety. Where others have eaten species which he has not had the opportunity to test, their names and opinions are given. When species heretofore under the ban of suspicion are in this volume, for the first time, announced to be edible (there are many of them), personal tests have not been considered sufficient, as idiosyncrasy might have affected the results. Others, at the writer’s request, have eaten of the species until their innocence was fully established. In some cases, where the reputation of the fungi eaten was especially bad, scientists of note have made elaborate and exhaustive physiological tests of their substances, and in every instance confirmed the human testing.

While species which contain deadly poisons are few, their individuals are produced in great number. Nicety in distinguishing their botanic variance from edible species closely resembling them is necessary. No charm will detect the poison. Eating toadstools before their certain identification as belonging to edible species, is neither bravery nor common sense. The amateur should go slow.

The question often asked is: By what rule do you distinguish between edible and poisonous mushrooms? The answer usually surprises the questioner—there is no general rule. All such rules which have been given are false and unreliable. The quality of each was learned, one at a time. Sweet and sour apples alike grow on large and small trees, may be red or green, large or small, oblong or globular, and no visible appearance gives the least clue to the quality.

In a few genera certain rules may be applied, as in Clavaria--all not bitter or tough are edible. But such generalizations are each limited to its own genus.

The toadstools containing deadly poisons are thought to be confined to one genus of the gilled kind—Amanita, and to Helvella esculenta, now Gyromitra esculenta, to which are charged fatal results. The poisonous qualities of Gyromitra esculenta are not proven. Recent testings of this species prove it to be harmless and of good quality. By far the greater number of species contained in Amanita are notable for their tender substance and delicious flavor. By their stately beauty and unusual attractiveness both the poisonous and harmless kinds are seductive. Any toadstool with white or lemon-yellow gills, casting white spores when laid—gills downward—upon a sheet of paper, having remnants of a fugitive skin in the shape of scabs or warts upon the upper surface of its cap, with a veil or ring, or remnants or stains of one, having at the base of its stem—in the ground—a loose, skin-like sheath surrounding it, or remnants of one, should never be eaten until the collector is thoroughly conversant with the technicalities of every such species, or has been taught by one whose authority is well known, that it is a harmless species. This rule purposely includes the renowned Amanita Cæsaria, everywhere written as luscious. I regard it as the most dangerous of toadstools, because of its close resemblance to its sister plant—the Amanita muscaria—which is deadly. In the description of these species, other forcible reasons are given.

Another deadly species—the Amanita phalloides—is frequently mistaken by the inexperienced for the common mushroom. Safety lies in the strict observance of two rules: Never eat a toadstool found in the woods or shady places, believing it to be the common mushroom. Never eat a white- or yellow-gilled toadstool in the same belief. The common mushroom does not grow in the woods, and its gills are at first pink, then purplish-brown or black.

If through carelessness, or by accident, a poisonous Amanita has been eaten, and sickness results, take an emetic at once, and send for a physician with instructions to bring hypodermic syringe and atropine sulphate. The dose is ¹⁄₁₈₀ of a grain, and doses should be continued heroically until the ¹⁄₂₀ of a grain is administered, or until, in the physician’s opinion, a proper quantity has been injected. Where the victim is critically ill the ¹⁄₂₀ of a grain may be administered.

In every case of toadstool poisoning, the physician must be guided by the symptoms exhibited. Professor W.S. Carter, by numerous exhaustive trials upon animals, has proved that atropine, while valuable as against the first, is not an antidote for the late effects of the greater toadstool poisons. (See his chapter on toadstool poisons, especially prepared for this work.)

There are other species which contain minor poisons producing very undesirable effects. These are soon remedied by taking an emetic, then one or two doses of whisky and sweet oil; or vinegar may be substituted for the whisky. A few species of fungi are innocuous to the majority of persons and harmful to a few. So it is with many common foods—strawberries, apples, tomatoes, celery, even potatoes. The beginner at toadstool eating usually expects commendation for bravery, and fearfully watches for hours the coming of something dreadful. Indigestion from any other cause is always laid to the traditionary enemy, fright ensues, a physician is called, the scare spreads, and a pestilential story of “Severe Poisoning by Toadstools,” gets into the newspapers. The writer has traced many such publications to imprudences in eating, with which toadstools had nothing to do.

The authoritative analysis of several common food species by Lafayette B. Mendel, of Sheffield Laboratory of Physiological Chemistry, Yale University, is given, and will correct the popular error about the great nutritive value of fungi, arising from previous erroneous analyses.

While species are reported as found in certain localities, it by no means follows that their growth is confined to these places. A species reported as found in the Adirondack mountains, unless belonging to the few peculiar to northern regions and high altitudes, is reasonably sure to be more plentiful in a like habitat south and west of them. South it will appear earlier and its season last longer.

Size is largely dependent upon latitude and may vary greatly in the same group. Temperature, moisture, favorable nourishment are important factors in growth.

Each species has its favorite habitat, and will thrive best upon it. There are few things under the sun upon which fungi do not grow. Their mission is particularly directed toward converting decaying matter, or matter which has accomplished its work in one direction, into usefulness in another. They are the wood-choppers, stewards, caterers of the forest, converters in the fields and chemists everywhere. They can not assimilate inorganic matter because of the absence of chlorophyl in their composition, but in organic matter they are omnivorous. When they feed on dead substances they are called saprophytes; when their support is derived from living tissues, parasites.

Scores of species of fungi were found in the forests, ravines and clearings of the West Virginia mountains from 1881 to 1885 inclusive, and eaten by the writer years before he had the opportunity to learn their names from books or obtain the friendly assistance of experts in identifying them. He knew the individuals without knowing their names, as one knows the bird song and plumage before formal introduction to the pretty creatures that charm him.

After he was able to get European publications upon the subject, and by their aid trace the species he had eaten to their names, descriptions and qualities, he was surprised to read that many of them were warned against as deadly. As informed by these books, he properly ought to have died several times. It soon became evident that authors had followed one another in condemning species, some because they bore brilliant hues, others because they were unpleasant when raw (just as is a potato), rather than investigate their qualities by testing them. Here was a realm of food-giving plants almost entirely unexplored. The writer determined to explore it. Instead of the one hundred and eleven species then recorded by the late Doctor Curtis as edible, my number of edible species now exceeds his by over six hundred.[^[A]]

[A]. This book contains one hundred and fifty pages more than were originally estimated and promised to the subscribers. That all known edible and poisonous species might be fully described and published within one volume, the author was compelled to cut fifty thousand words from his manuscript. The localities from which species have been reported and the names of the reporters have been taken out, excepting where it was desirable to show that foreign species have been found in the United States, and where tested species have been found by the author. The principal cut has been from the notes of the author and of enlarged descriptions.

Let us clear away the rubbish and superstition that have so long obscured the straight path to a knowledge of edible toadstools. Let us bear in mind that a mushroom is a toadstool and a toadstool is a mushroom—the terms are interchangeable. If toads ever occupied the one-legged seat assigned them from time immemorial, they have learned in this enlightened age that the ground is much more reliable, and so squat upon it, except when exercising their constitutional right to hop. Snails, slugs, insects of many kinds, mice, squirrels and rabbits prey upon good and bad, each to its liking, notwithstanding oft-repeated assertion that snails and slugs infect noxious varieties only, or that animals select the innocuous only. We are warned against those which grow in the dark or damp; the mushroom of commerce is grown by the ton in the subterranean quarries of France, and everywhere in vaults and cellars for domestic use. The valued truffle never sees the light until it is taken from darkness to be eaten, and other varieties of the best prefer seclusion.

The wiseacres tell us that they must have equal gills, must not have thin tops, must not turn yellow when sprinkled with salt, must not blacken a silver spoon, that we must not eat of those changing color when cut or broken, of those exuding milk, or those which are acrid, hot, or bitter, and give many other specifics for determining the good from the bad. These tests are all worse than worthless, for if confidence is placed in them they will not only lead us away from esculent and excellent varieties but directly into eating venomous ones.

There are whole genera of fungi which are innocuous; but in the Family of Agaricaceæ, where the greatest variety of the edible and poisonous species are found, it is necessary to master one by one the details of their construction and learn to distinguish their differences as one does those of the many kinds of roses, or pinks, or hundreds of bright-faced pansies, and in the mastery of them lies the only charm that will safely guide.

Carefully remove the first toadstool found from whatever it is growing upon, and with it a portion of that from which it springs. If it is the earth a curious white network is discernible, fine as the delicate spinning of the spider, spreading its meshes throughout the mass. It will often remind of miniature vines climbing over miniature lattices. This is the mycelium from which the toadstool grew. In many instances it penetrates the earth to a considerable depth, and takes possession of large territory. It is often seen as the gardener turns up the soil or its fertilizer, and is perhaps taken for a mold. If the specimen is gathered from mat of wood leaves, the same white vine is observable slipping in between its layers. If taken from a tree, the decaying wood is traversed by it. From wherever a toadstool is plucked, it is removed from its mycelium.

This mycelium is but a thread-like mass of simple cells joined together at their ends and interlacing in a way a thousand-fold more intricate than a Chinese puzzle. Nothing in its structure indicates what its special product will be. The fungus which is plucked from it is in all its parts simply a mass of these threads—cells strung together, interlacing and ramifying.

When the season favors, the mycelium—which has, winter and summer and from year to year, lived its hidden life, or has sprung from a germinating spore—develops a number of its cells in a minute knob, small as a pin head. At this point the cells make special growth efforts to bring themselves within the favoring influences of heat and moisture; this tiny knob labors within itself, producing cell after cell, which takes shape and function for the future toadstool.

As it rapidly enlarges it pushes its way toward the surface of the ground, becomes more or less egg-shaped in this stage of its growth, and if cut in half longitudinally and examined, it will display what it is going to be when it grows up.

Suppose that it belongs to the first of the two great sections into which fungi are divided under the classification of Fries, who modified that of Persoon. The first has the spores—which represent the seeds in plants—naked, and it is called sporifera or spore-bearing. The second, which has the spores enclosed in cells or cysts, is called sporidifera or sporidia-bearing. If the cap of a gill-bearing toadstool be laid, gills downward, on a watch crystal or piece of white paper for a few hours, or, in some instances, a few minutes, a complete representation of the spaces between the gills will be found deposited as an impalpable powder. These are the spores.

The first section is divided into four cohorts. Two of these have hymeniums or spore-bearing surfaces more or less expanded. These are Hymenomycetes and Gastromycetes. In Hymenomycetes the hymenium is always exposed in matured plants, as with the common mushroom. When young, some plants are covered with a membrane. In Gastromycetes the hymenium is always concealed within a covering which bursts at maturity, as with the Lycoperdons or puff-balls. Cohort Coniomycetes includes rusts, smuts, etc., formed for the most part on living plants. There is no hymenium present. The spores are produced on the ends of inconspicuous threads, free or enclosed in a bottle-like receptacle called a perithecium. Cohort Hypomycetes is composed of those species of fungi commonly called molds. The spores are produced, naked, from the ends of inconspicuous threads.

In the Agaricaceæ—the first family in Hymenomycetes—the young plant is completely enveloped. (Plate [III], fig. B, p. 2.) Its head is as yet undefined and its body may be classed as dumpy, but shut in and protected are a great quantity of knife-like plaits (Plate [III], fig. C., p. 2), on the outer surface of which, when the plant matures, will be borne its spores. It therefore belongs to the Hymenomycetes, and to the Family Agaricaceæ—gill-bearing.

If the ground becomes moist or there comes a heavy dew or a rain, the young plant, closely compacted and very solid, which has been under the surface for many days waiting its chance to get forth to light and air, rapidly swells, breaks through the moistened earth, goes rapidly to cell-making, ruptures its outside covering, the head expands and in so doing spreads out its gills or hymenium. (Plate [III], figs. C, D, E, p. 2.) The membrane which covered the gills either vanishes, or gathers round the stem in the form of a ring or circular apron, or it may partially adhere to the edges of the top, cap or pileus and hang as a fringe from it; the stem elongates; the whole plant assumes the colors of its species and in a few hours or days at most it stands forth, a marvel of beauty, structure and workmanship.

But little is known of how these spores reproduce themselves. The microscope fails to completely penetrate the mystery. A whole fungus is but a mass of cells, the spore is but one of them. That these simple cells do produce after their kind there is no doubt, but so minute is the germ and hidden its methods that science has failed to solve them.

The first Family of Hymenomycetes is Agaricaceæ. Its members always have gills or modifications of them. In some cases—notably in Cantharellus—the gills have the appearance of smooth, raised veins over which is the spore-bearing surface. The hymenium is but an extension of the fibers of the cap, folded up like the plaits and flutings of ruffles, and laundered with exquisite neatness. If it is carefully detached and spread out like a fan it will cover a large surface, many times the size of the cap from which it has been taken, and will show that what is a consumption of material in dress ornamentation is utilized by economical Dame Nature to increase the spore-bearing surface within a small space and for purely business purposes—spore-bearing. The color of these spores has much to do with the classification. The microscope with high light reveals the delicate shades of their coloring, but the main colors are readily distinguished by the naked eye when the spores are collected in a mass on glass or paper.

The Polyporaceæ have in place of gills closely packed tubes on the inside of which is the spore-bearing surface; each has a mouth from which to eject the spores.

The Hydnaceæ bear their spores from spines or spicules of various length protruding from the external surface of the cap. Sometimes the spines mock in miniature the stalactites of the Caverns of Luray, sometimes the shaggy mane of the lion, sometimes flowing locks of hair. These three Families belong to the Cohort Hymenomycetes, having their spore-bearing surface exposed early in life by the rupture of the universal veil.

The Lycoperdons or Puff-balls have the hymenium enclosed within an outer case, just as the apple with its seeds is enclosed for a dumpling. When the spores are matured the sack is ruptured and they escape as the dusty powder so well known to all. The Puff-ball belongs to the Cohort Gastromycetes, because its spores are protected within the hymenium until they are matured.

There are other Families which contain edible species. The Clavariaceæ—branched or club-shaped—often found in as beautiful forms as delight us in coral, includes a few.

In Ascomycetes, of the covered spore division Sporidifera, there are several species which are excellent, and as they dry readily are much valued for flavoring purposes when winter forbids the growth of outdoor fungi. Of these the Morell has preference. The cap is covered with sinuosities and pits which bear the spores. There are several varieties of the Morell in the United States. They are known among the country people who cook and pickle them, as Honey-comb mushrooms.

The Tuberaceæ are subterranean fungi. The common truffle so much prized by epicures is a good representative. It is found a foot or more under the surface of the earth, and of such value is it that in some countries pigs are trained to hunt it from its hiding place. It is one of the few foreign growths apparently not taking kindly to our country. Efforts have been made to import and cultivate it, but without success. It is possible, even probable, that it may yet be found in America by assiduous search.

I have said that there is but one way to distinguish the edible from the non-edible fungi; that is by mastering the characteristics of each species one by one. There are signs which point to the evil and those which point to the good, but they must be used as signals, not directors.

A nauseous, fetid odor should condemn a species as non-edible at once. Those having the flavor of flour or fresh meal are generally accepted as worthy of trial. Slimy, water-soaked, partially decomposed plants, or those impressing one as unpleasant in any way, should never find their place upon the table. Do not eat of any toadstool, unknown to the collector, beyond the careful and systematic testing required to determine whether it is edible or not.

A few species have a serious charge remaining against them; that of partiality. They unmistakably signify with whom they will agree and with whom they will not. These are notably Clitocybe illudens, Lepiota Morgani, Panæolus papilionaceus, all specialized in their places in the text.

Other species have hereditary taints upon their reputations. Most, if not all of them have stood present tests and relieved themselves of suspicion. But, alas that it should be so! The stigma must rest upon them for yet a while and until their defenders are so numerous that their purity, without a smirch, is popularly proclaimed.

Wherever wood grows and decays as it will, Polyporus, Panus, Lenzites, Schizophyllum and kindred genera stand prominently forth in countless numbers. The great majority of them are inedible because of their woody substance. A few are valued as food. Very many of them yield their soluble matter and flavor when boiled, and in this way make excellent soups and gravies, just as flax-seed and the bark of the slippery elm yield succulent matter. These, however, are not, with a few exceptions, mentioned in this book. Numbers of Clavarieæ and Hydneæ are in the same category. M.C. Cooke tersely says: “Fruits that are not peaches or apricots may be very good plums.” In the introductions to genera their attributes are given; under “Instructions to Students” every guide to identification and selection will be found.

A Glossary, containing the botanic terms used in this book and, it is believed, all other terms used by mycologists in describing fungi, follows the descriptive text. It is strongly advised that it be carefully studied. The roots and derivatives of the botanic terms are fully and carefully given by Dr. John W. Harshberger, professor of botany, University of Pennsylvania, to whom the author is specially indebted.

The excellent Glossary published by Dr. Edwin A. Daniels, Boston, has furnished many comprehensive definitions. It is the property of the Boston Mycological Club, and can be obtained from its secretary for twenty-five cents.

The determination of the proper accentuation of the generic and specific terms has been in many cases a difficult task, and, in some cases, owing to the dubious origin of the words in question, there is certainly room for difference of opinion. This task has been kindly and conscientiously performed by Prof. M.W. Easton, professor of Comparative and English Philology, University of Pennsylvania. Thanks are due to the Hon. Addison Brown, president of the Torrey Botanical Club, and Dr. Nathaniel L. Britton, professor of Botany in Columbia College, authors of “Illustrated Flora,” for the determination of the accentuation of non-classical words ending in inus.

Three indexes are given: the first refers to the general contents, the second to the genera, the third to species and their genera, alphabetically arranged.

Mrs. Emma P. Ewing and Mrs. Sarah T. Rorer have kindly furnished some of their recipes for the preparation of several varieties of toadstools. The best results of the author’s long experience in cooking toadstools are given in the chapter “Recipes for Cooking and Preparing for the Table,” together with others selected from many sources. The personal taste of the server must be guide to the choice.

A child-friend of the writer, in telling him of her mother’s cook, said: “She’s a good cooker, but she has a bad temper.” A good “cooker” will soon learn how to best display the individual flavor of each species. And be it known that each species of toadstool has a flavor of its own. These flavors vary as much as among meats and vegetables. No one species can be taken as standard of excellence.

The greatest care has been taken to secure illustrations correct in every botanic detail. With few exceptions the colored figures were drawn and painted by the writer. To obtain this important feature the requirements of art have frequently been sacrificed. An artist can make a picture of a toadstool; the mycologist must guide his brush or pencil in the making of a correct presentation. The happy combination of artist and mycologist occurs in Mr. Val. W. Starnes, Augusta, Ga., to whom this volume owes many of its illustrations. Mr. Frank D. Briscoe, widely known as an artist of rare ability, has arranged and painted in groups the studies made by the writer from typical plants, and added to the illustrations many excellent drawings of his own.

The unfailing reliability of the sun has been masterfully used by Dr. J.R. Weist, ex-Secretary of the American Society of Surgeons, Richmond, Ind.; H.I. Miller, Superintendent Terre Haute and Indianapolis Railroad, Terre Haute, Ind., and Mr. Luther G. Harpel, Lebanon, Pa., in making the unexcelled photographs generously contributed by them. The author is most thankful to them and to Mr. C.G. Lloyd, Cincinnati, Ohio—a scientific gentleman devoting lavishly of his time and money to the spread of mycological knowledge—for the privilege of selecting from his extensive collection of realistic photographs those adaptable to the species described herein.

The author’s thanks are gratefully given to the many who have by help and encouragement furthered his efforts in producing this, the first American text-book upon fungi. Space precludes the naming of the many, but the few named do not outrank them in their interest, help and the author’s appreciation:

Miss Lydia M. Patchen, President of the Westfield, N.Y., Toadstool Club (the first in America); Mrs. E.C. Anthony, Thomas J. Collins, E.B. Sterling, Berry Benson, Melvil Dewey, New York State Librarian; Dr. J.E. Schadle, Prof. J.P. Arnold, University of Pennsylvania; Prof. W.S. Carter, University of Texas; Boston School of Natural History; Massachusetts Horticultural Society; Prof. Wm. G. Farlow, University of Harvard.

Thus aided the author believes that his own conscientious, patient, loved labor in the study of edible and non-edible fungi and the production of this volume will be far-reaching in its one object—encouraging the study of toadstools.

The time for writing a complete flora of the United States has not yet come; a large part of the country remains as yet unexplored by mycologists; new species are being constantly discovered in the districts best known. Every book on the subject must be necessarily incomplete.

On the other hand, so far as concerns the known fungus-flora, there is imperative need of some guide to the student, which shall at least save him some part of the weary toil of hunting through the scattered literature in which alone, as things are at present, can be found the information he seeks. In this book I have tried to meet this need. It is not complete, but I have tried to so arrange the matter that the student can always decide whether the particular specimen in hand is or is not included, and, at least for all of our more conspicuous fungi, determine the family and genus. If the student can do so much, the task of finding the specific name, even when not included in this book, becomes very much simpler.

So much for the more scientific aspect of my book. But I have also kept in constant view the needs of the large and constantly growing number of persons who have no aim further than to learn to know the principal toadstools seen in their walks, just as they wish to know the principal trees and the more conspicuous birds. For such as these, the difficulty of deciding whether or no a particular individual fungus is described in the brief (sketching) manuals hitherto accessible is even more formidable than with the special student of botany.

Finally, I have kept in view throughout the work the needs of the mycophagists. They are not pot-hunters; they care much less for the physical pleasure of the appetite than for the close study of Nature that their inclination leads them into. Some day the delights of a mushroom hunt along lush pastures and rich woodlands will take the rank of the gentlest craft among those of hunting, and may perchance find its own Izaak Walton.

Author’s and Publisher’s Note.

It is the intention of the author and the publisher to keep this book up to date. Recognizing that future testing will prove many more species of toadstools to be edible, and that scientists will have more exact knowledge of toadstool poisons and their antidotes, they announce that illustrated sheets publishing new edible species and current information upon fungi will be, from time to time, issued, conforming in shape and style to this volume and at an acceptable price.

That the author and publishers may keep in touch with the owner of each volume, and be informed of new discoveries in species and of new experience, owners are requested to communicate their book numbers to Captain Charles McIlvaine, or the Bowen-Merrill Co., Indianapolis, Ind.

INSTRUCTIONS TO STUDENTS

To catch fish one must know more than the fish; to find toadstools one must know their season and habitats. They are propagated by their spores and from their mycelium—that web-like growth which is the result of spore germination.

The spores of ground-growing kinds, when shed upon the ground, are washed by rains along the natural drainage; therefore, when a specimen of one of these kinds is found, it is well to look up and down the natural water-shed, and follow it. Good reward will usually come of it. Few fungi are strictly solitary.

Careful observation of the habitats of the various genera and species will enable the student to know what may and may not be expected in a particular locality, and will save many a hunt.

When an unknown species is found, collect it carefully, examine it closely, note all its features. Determine to which division of fungi it belongs. If to the gilled family (Agaricaceæ) obtain the color of the spores (see directions). Look at the chart “Tabular View of Genera of Agaricaceæ,” Plate [I], p. 2 (after W.G. Smith, but enlarged, redrawn and emended). If the spores are white, it belongs to one of the genera in the first column—Leucosporæ; if pink, to one in the second column, and so on. It is often difficult to determine the spore color, because spores vary through many shades of the typical color. What are called white spores may be creamy, dirty, yellowish or brownish-white; pink spores will vary from almost white to reddish and salmon-color; brown spores from light-ochraceous through cinnamon to rusty; purple spores from dark-violet to purplish-black. Experience alone will enable the student to decide which color series is present. The Genera Charts, preceding the five different color series, show typical spore colors only. Again, authors describing the species frequently fail to see colors alike; if they do, their names for them frequently vary. For instance, few persons will agree upon a color expressed as “livid.”

The color system principally used by botanists is Saccardo’s “Chromotaxia,” costing fifty cents. It is decidedly inadequate. Ridgway’s “Nomenclature of Colors for Naturalists” is far better, but it is out of print and obtainable only at the principal libraries. “The Prang Standard of Color” is the most complete ever issued, but it is inapplicable to existing descriptions of fungi.

Make and Preserve Spore Prints.

Take, to print upon, sheets of Bristol-board or any stiff, hard-surfaced white paper 6×9 inches or larger. Cut a round hole, four inches in diameter, in one of the sheets. Use this as a stencil. Lay it upon a print-sheet and where the opening occurs, paint with a weak solution of gum arabic—⅛ oz. (one teaspoonful) to one pint of water. Dry the print-sheets.

When a spore-print is to be taken, select a fully-grown specimen, remove the stem, place the spore-bearing surface upon the gummed paper, cover tightly with an inverted bowl or saucer, and allow to stand undisturbed for eight or ten hours. The moisture in the plant will soften the gummed surface; the spores will be shed and will adhere to it, making a perfect, permanent print. When the print is plain, remove the specimen carefully and dry the print. Number the print-cards to correspond with the number of the specimen in the “Record of Fungi,” and place them in a box or cover. Some genera shed their spores sooner and more freely than others. A surplus of spores is objectionable. In order to know when a print is plainly made, without disturbing the process, have either a specimen of the same age, or a piece of the one under the bowl, on another piece of gummed paper, covered in like manner. This can be examined and will give the desired information. A little experience will enable the student to obtain good and lasting prints.

The large black figures on some calendars, if cut with the white about them, are convenient as trial sheets for spore-printing. Lay the specimen partly on the white, partly on the black. If the spores are light, they show best on black ground, and if colored, they show best on the light.

Spore measurements, as given by different observers, vary to such a degree that they are of little value, excepting as determining a few species, but spore shapes and characteristics are of use as a last resort, in accurate determinations. A microscope of considerable power is needed.

A metrical scale and table of measures is here given, that the student may have a present guide to such measurements as are given in mycological publications.

Measures

Decimetre.

Use of Charts of Genera.

The spore color being determined, turn to the Genera Chart, showing spores of like color. Ascertain from the specimen whether or not its cap or hymenophore is distinct or easily separable from the stem and the gills free from the stem; if they are, it may belong to one of the genera in the upper row of figures; if the cap is not easily separable nor the gills free, look at the shape of the gills, and find on the chart a corresponding gill-shape. It is probable that the genus can thus be determined. Then turn to this genus in the text, read the heading, look over the “Analysis of Tribes,” go to the tribe nearest in designating the properties of the specimen; comparing the specimen with the descriptions of species given thereunder, will probably enable the seeker to decide upon its name.

It should be remembered that the descriptions in the text are of the specimen or specimens which the author of the species saw. What the author says fixes the type of the species. Specimens of the species may, and very frequently do, vary greatly from the type. If the first attempt to fix the genus is not satisfactory, try again, and keep on trying until reasonably sure. The amateur will find, however good an opinion may exist in his mind of the stock of patience on hand, that the territory of patience has just been reached.

Making and Preserving Notes.

An excellent blank form for “Collectors’ Notes” is published by the Boston Mycological Club, at one cent. It is desirable that there should be uniformity in collectors’ notes, and that they should be as full as possible. A form of this, or a similar kind, should be filled in and kept, and should also be used when specimens are sent to an expert for identification. Such specimens should be fresh, wrapped separately in tissue paper, numbered, and a few should be packed in a box that will not crush in the mail. The address of the sender should be upon the outside. The collector’s notes should be sent in a letter, with a postage stamp for reply enclosed. If the specimens have to go a great distance, they should be partially dried in a slow, open oven, or they will be a rotten mass when they reach their destination.

To Test Edibility of Species.

There is but one way by which to determine the edibility of a species. If it looks and smells inviting, and its species can not be determined, taste a very small piece. Do not swallow it. Note the effect on the tongue and mouth. But many species, delicious when cooked, are not inviting raw. Cook a small piece; do not season it. Taste again; if agreeable eat it (unless it is an Amanita). After several hours, no unpleasant effect arising, cook a larger piece, and increase the quantity until fully satisfied as to its qualities. Never vary from this system, no matter how much tempted. No possible danger can arise from adhering firmly to it. Recipes for preparing, cooking and serving are given in chapter on cooking.

It is better for the student to first become familiar with the common species, one at a time, than to attempt tracing the rare or many. Worry, fatigue and uncertainty are plentiful in an indiscriminate gathering of fungi. One species a day, properly traced and named, means learning three hundred and sixty-five species a year.

The Glossary.

Unfamiliar terms will be encountered in the descriptive text. The Glossary defines them; and not only those in this book, but, it is believed, all those found in other books upon fungi. Where possible throughout the text, botanical terms have been anglicized. The meanings of those remaining unchanged should be memorized. It is quite as easy, and far better, to learn the botanical names of species and their characteristics, as to learn their common names; easier in fact, for the common names often vary with locality. The writer received a letter from an Alsatian living in St. Louis, telling him of favorite fungi he used to eat when in his own country. To all he gave local names, not one of which could be referred to the particular species meant.

Success and pleasure in the study of fungi will attend the student who observes carefully and who systematically records that which is observed.

CLASS, FUNGI

Sub-Class BASIDIOMYCETES

Cohort HYMENOMYCETES. Gr.—a membrane, a fruit-bearing surface; Gr.—a mushroom. (So called from the hymenium or fruit-bearing surface.)

Fungi composed of membranes, fleshy, woody or gelatinous, growing on wood or on the ground. The hymenium or spore-bearing surface exposed at an early stage. The spores are borne on basidia, spread over the surface. The common mushroom is typical of the family. All the members resemble it, more or less, in organization and reproductive organs. These latter, in the mushroom, are spread over lamellæ or gills. The spores, after ripening and dissemination, germinate and produce a mycelium or thread-like vine, which in turn develops the spore-producing part of the plant. Hymenomycetes is divided into the following six Families:—

a. HYMENIUM FIGURATE.

b. HYMENIUM EVEN.

FAMILY I.—AGARICACEÆ.

In the Agaricaceæ the hymenium is spread over lamellæ or gills which radiate from a center or stem. The gills are composed of a double membrane, and are simple or branched.

The parts of an Agaric may all be present as in Amanitæ, or severally absent in other genera. When the young fungus is entirely enclosed in a wrapper or case, this case is called the universal veil. When this veil is ruptured by the growth of the stem, that part which remains attached to the base is called the volva. The membrane reaching from the stem to the margin of the cap is the partial veil; when it ruptures by the expansion of the cap and all or a portion adheres to and about the stem it forms the annulus or ring. In some species one or both veils may be present, or one or both may be absent.

The stem is central when supporting the cap at its center; excentric when at one side of the center; lateral when it supports the cap from the side. If the stem is absent, the cap is said to be sessile; if the cap is horizontal and supported by a broad base it is dimidiate; if attached to its place of growth by its back it is resupinate.

Genera are largely distinguished by the manner in which the gills are attached to the stem. These distinguishing attachments are shown in the plates illustrating genera and in Plate [IV]. Gill-shapes.

For convenience Agaricaceæ is divided by the color of the spores into five series: white, pink, brown, purple, black. The last two, owing to the similarity of hue, are by some writers (preferably) included in the black-spored series. Spore color is a valuable assistant in determining species.

Series I. LEUCOSPORÆ. Gr.—white; Gr.—seed.

Spores white, rarely dingy or inclining to reddish. In the genus Russula the spores of some species are white, in some cream-color, and in several pale ochraceous. Variations from pure white are found in the spores of Tricholoma personatum and a few other species. Gill-color is not a guide to spore-color. Purple, yellow, brown, pinkish gills may produce white spores.

Plate I.

Plate II.

AMANITA.

(A name given to some esculent fungi by Galen, perhaps from

Mount Amanus.)

Universal veil (volva), which is at first continuous (completely enveloping the young plant), distinct from the skin of the cap. Hymenophore or cap, the part which bears the spore-bearing surface, distinct and easily separable from the stem, which leaves a socket in the flesh when it is removed. All growing upon the ground. Fries.

(Plate VII.)

Section of Amanita Phalloides.

Pileus somewhat fleshy, convex then expanded. Gills free. Universal veil at first enclosing the entire plant, which as it grows bursts through, generally carrying the upper part on the pileus, where it appears as patches or scales, the remainder enclosing the stem at the base as a volva, either in a cup-like form, closely adherent or friable and evanescent. The partial veil in youth extends from the stem to the margin of the pileus, enclosing the gills; when ruptured it depends from the stem as a ring. Stem furnished with a ring, and different in substance from that of the pileus. Spores white.

On the ground.

The nearest allied genus, Amanitopsis, is separated by the absence of a ring, and Lepiota by its lack of a volva; Volvaria, Acetabularia and Chitonia, possessing volvas, are distinguished by the color of their spores.

Amanitæ are the most beautiful and conspicuous of fungi. While there are comparatively few species of them, the individual members are plentiful in appearing from spring until the coming of frost. They are solitary or gregarious in growth. Occasionally two or three are found together. They frequent woods, groves, copse, margins of woods and land recently cleared of trees. They are seldom found in open fields. A careful study of all their botanic points should be the first duty of the student of fungi. Familiarity with every characteristic of the Amanitæ will insure against fatal toadstool poisoning, for it is the well-grounded belief of those who have made thorough investigation that, with the exception of Helvella esculenta, now Gyromitra esculenta, the Amanitæ, alone, contain deadly poisons.

No Amanita, or piece of one, should be eaten before its identity is fully established and its qualities ascertained by referring to the descriptions herein given or to the opinion of an expert.

They are the aristocrats of fungi. Their noble bearing, their beauty, their power for good or evil, and above all their perfect structure, have placed them first in their realm; and they proudly bear the three badges of their clan and rank—the volva or sheath from which they spring, the kid-like apron encircling their waists, and patch-marks of their high birth upon their caps. In their youth, when in or just appearing above the ground, they are completely invested with a membrane or universal veil, which is distinct and free from the skin of the cap. As the plant grows the membrane stretches and finally bursts. It sometimes ruptures in one place only and remains about the base of the stem as the volva. When such a rupture occurs the caps are smooth. In most species portions of the volva remain upon the cap as scruff or warts—pointed or rough—or as feathery adornment; any or all of which may in part or whole vanish with age or be washed away by rain.

Extending from the stem to the margin of the cap, and covering the gills, is the partial veil—a membranaceous, white texture of varying thickness. As the cap expands this veil tears from it. Portions frequently remain pendant from the edges, the rest contracts to the stem as a ring, or droops from it as a surrounding ruffle, or, if of slight consistency, may be fugacious and disappear, but marks, remains, or the veil itself will always be traceable upon the stem.

The Amanitæ are of all colors, from the brilliant orange of the A. Cæsarea, the rich scarlet or crimson of the A. muscaria, to the pure white of the A. phalloides in its white form.

Their stems are usually long, and taper from the base toward the top. In some forms the base is distinctly bulbous. The volva at the base is attached to the stem at its lower extremity. It may be visible as a cup or ruptured pouch with spreading mouth, or it may be of such friable texture as to appear like mealy scales. Often, when the plant is pulled from the ground, the volva remains, but the marks of its attachment will appear and should be carefully looked for. Their gills are commonly white, are of equal length and radiate from near the stem, which they do not reach, to the circumference of the cap. They are white, unless tinged with age, excepting upon A. Cæsarea and A. Frostiana where they are yellow.[^[B]] Their caps are umbrella-shaped, flat or convex. Their flesh is white, does not change color when bruised. They are scentless and almost tasteless when fresh, when old they have a slightly offensive odor and taste.

[B]. A. Frostiana is not always yellow gilled.

The family is not a large one, not over thirty members complete its circle. Every feature, every part of its several members, should be thoroughly known before the intimacy of eating. While at least nine of the family are not only edible but delicate and sapid, far better will it be to leave all alone than to make a mistake. A piece of a poisonous variety the size of a dime will often cause serious disorders if eaten. Many persons have died from eating very small quantities.

Because of its ovate or button-like form when young, it is frequently mistaken for the common field mushroom; even experienced mycophagists have been deceived by it. No other poison has so puzzled scientists. Other varieties of fungi may interfere with digestion, but to the Amanitæ all deaths from toadstool-eating are traceable. Its subtle alkaloid is absorbed by the system, and in most cases lies unsuspected for from six to twelve hours, then its iron grip holds to the death. For centuries it has defied all remedies. The problem has been partially solved. At Shenandoah, Pa., August 31, 1885, a family of five were poisoned by toadstools; two died, three lived. Noting the sad account in the newspapers, I at once wrote to Shenandoah for specimens of the fungi eaten and a description of the treatment. I promptly received from Dr. J.E. Schadle (now Professor Schadle), the physician in charge of the cases, a box containing two harmless varieties and several fine specimens of the Amanita phalloides, all of which were gathered on the same spot and by the same person who gathered the toadstools doing the poisoning. They told the tale. A remarkably full and interesting account of the cases was sent to me by Dr. Schadle. After exhausting all other remedies, and after two of the five had died, he administered subcutaneously, by hypodermic injection, sulphate of atropine—a product of the deadly nightshade analagous to belladonna—¹⁄₁₈₀ to ¹⁄₆₀ of a grain at a dose. It proved to be an antidote and saved the lives of the remaining three.

The action of atropine in arresting the deadly work of poisoning by amanitine had been foreshadowed by Schmidberg and Koppe, and dwelt upon in numerous published articles by Mr. Julius A. Palmer, to whom more than any other is due the branding of the murderous members of the Amanita family; but for the first time atropine was used upon the human system to ward their blows.

All of the species herein described are found in the United States. Of the twenty-seven, nine are edible, nine are either known to be deadly or are so closely allied to deadly species that it is unsafe to class them as other than poisonous until absolute proof is obtained of their harmlessness. The remaining nine I have not seen, neither is there any record of their qualities.

ANALYSIS OF SPECIES.

[*] Volva opening at the top or splitting all around, leaving a manifest, free border at the base of the stem. Pileus naked or with broad membranaceous patches.

[**] Volva splitting regularly all round the lower portion, persistent, more or less closely embracing the base of the bulbous stem. The upper portion being adnate to the pileus appears on it by expansion as scattered, thick warts.

[***] Volva friable, entirely broken up into wart-like scales, therefore not persistent at the base of the stem, which is at first globose-bulbous, becoming less so as it lengthens. Pileus bearing mealy patches, soon disappearing or with small, hard, pointed warts.

[****] Volva rudimentary, flocculose, wholly disappearing.

* Volva bursting at top, etc.

A. viro´sa Fr.—virus, poison.

Shining white. Pileus 3–4 in. broad, fleshy, at first conical and acute, afterwards bell-shaped, then expanded, naked, viscous in wet weather, shining when dry, margin always even, but most frequently unequal, turned backward and inflexed. Flesh white, unchangeable. Stem 4–6 in. long, wholly stuffed, almost solid, split up into longitudinal fibrils, cylindrical from the bulbous base, often compressed at the apex, torn into scales on the surface, springing from a lax, wide, thick volva, which bursts open at the apex. Ring close to the top, lax, silky, splitting up into floccose fragments. Gills free, thin, narrow, narrowing at both ends, but a little broader in front, not decurrent on the stem (although the apex of the stem is often striate), crowded, somewhat floccose at the edge. Fries.

The pilei are most frequently oblique, extended and lobed on one side as in Hygrophorous conicus, scarcely ever depressed. The pileus rarely becomes yellow. The fragments of the veil often adhere to the edge of the gills.

Spores spheroid or subspheroid, 10–16µ, K.; 8µ W.P.; sub-globose, 8–10µ Massee.

POISONOUS.

I think it a variety of A. phalloides.

A. phalloi´des Fr. Gr.—phallus-like. (Plate [VI], figs. 2, 3, p. 6.) Pileus 3–4 in. broad, commonly shining white or lemon-yellow, fleshy, oval bell-shaped, then expanded, obtuse, covered over with a pellicle which is viscid (not glutinous) in wet weather, naked, rarely sprinkled with one or two fragments of the volva, the regular margin even. Stem 3–5 in. long, ½ in. and more thick, solid downward, bulbous, hollow and attenuated upward, rather smooth, white. Ring superior, reflexed, slightly striate, swollen, commonly entire, white. Volva more or less buried in the soil, bulbous, semifree, bursting open in a torn manner at the apex, with a lax border. Gills free, ventricose, 4 lines broad, shining white. Fries.

Pileus very variable in color, commonly white or yellow (A. citrina Pers.), becoming green (A. viridis Pers.), olivaceous and occasionally variegated with tiger spots; in late autumn with the disk almost black but whitish round the margin. Odor somewhat fetid, but little remarkable as compared with that of A. virosa.

In woods. Frequent. August to November.

A very POISONOUS and dangerous species. Stevenson.

Spores 8–9µ W.G.S.; 8–10µ B.; 7–9µ diam. Massee; globose, 7.6×6µ Peck.

Pileus at first ovate or subcampanulate, then expanded, slightly viscid when young and moist, smooth or rarely adorned by a few fragments of the volva, even on the margin, white, yellowish-brown or blackish-brown. Lamellæ rather broad, rounded behind, free, white. Stem equal or slightly tapering upward, stuffed or hollow, smooth or slightly floccose, ringed, bulbous, the ruptured volva either appressed loose or merely forming a narrow margin to the bulb.

Plant 4–8 in. high. Pileus 2–5 in. broad. Stem 3–6 lines thick.

This species is common and variable. It occurs everywhere in woods and assumes such different colors that the inexperienced mycologist is apt to mistake its different forms for distinct species. With us the prevailing colors of the pileus are white, yellowish-white, grayish-brown and blackish-brown. It is remarkable that the form with a greenish pileus, which seems to be common enough in Europe, does not occur here. Fries also mentions a form having a white pileus with a black disk. A somewhat similar form occurs here, in which the pileus is grayish-brown with a black disk. Some of the variously colored forms were formerly taken to be distinct species, in consequence of which several synonyms have arisen, of which A. virescens Fl. Dan., Amanita viridis Pers., and Amanita citrina Pers., are examples. A. verna Bull. is a variety having a white pileus, a rather thick annulus and an appressed volva. It sometimes occurs early in the season; hence the specific name. It also occurs late in the season and runs into the typical form so that it is not easy to keep it distinct. The flesh and the lamellæ are white, the stem is white, pallid or brownish, and the annulus is either white or brownish. The bulb is generally very broad and abrupt or depressed, though it sometimes is small and approaches an ovate form. The large bulbs are sometimes split externally in two or three places and are, therefore, two- or three-lobed. In such cases the volva is less persistent than usual and its free portion then furnishes merely an acute edge or narrow margin to the bulb. Specimens sometimes occur in which the margin of the pileus is narrowly adorned with a slight woolly hairiness, but usually it is perfectly smooth and even. By this character, taken in connection with the membranous volva and bulbous base of the stem, the species is readily distinguished. Sometimes a strong odor is emitted by it, but usually the odor is slight. Authors generally pronounce this a poisonous and very dangerous species. Its appearance is attractive, but its use as food is to be avoided. Peck, 33d Rep. N.Y. State Bot.

Common in woods and recently cleared woodlands. Frequent over the United States. June to frost.

An exceedingly poisonous, dangerous, seductive species, responsible for most of the deaths from toadstool eating; because in its white form it is mistaken for the common mushroom—Agaricus campester. The real fault is with the collector, who should never eat any fungus found in the woods, believing it to be the mushroom. The mushroom does not grow in the woods. Neither has it white gills, nor white spores, nor a volva at the base of the stem as have Amanitæ.

The caps of A. phalloides vary in color—white, oyster-color, smoky brown. The color of the commonest form is from white to a light hue of greenish yellow. The center of the cap, whatever may be the prevailing color, is usually several shades darker. In shape, the cap changes from a knob in youth, through the shapes of expansion, until it becomes fully spread, when it is umbrella-shaped, or almost flat. Some forms have a slightly raised portion or umbo in the center of the cap. The gills are white, of good width, rounded next to the stem and free from it.

The stem conforms in color to the cap, but in lighter shades. White-capped varieties have white stems. The stem has a sudden broad, distinct bulb at the base. On the upper side of the bulb there is usually a margin or rim. The stem tapers more or less toward the cap, from which it is easily separable. The cup, wrapper or volva is torn or split or irregular at the upper part, and is not pressed to the stem as in some forms.

Professor Peck, in his 48th Report, gives the following excellent synopsis of differences between the poisonous Amanita and edible fungi, for which it could only by great stupidity be mistaken:

Poison amanita. Gills persistently white. Stem equal to or longer than the diameter of the cap, with a broad, distinct bulb at the base.

Common mushroom. Gills pink, becoming blackish-brown. Stem shorter than the diameter of the cap, with no bulb at the base.

From all forms of the edible Sheathed amanitopsis the Poison amanita differs in its distinctly bulbous stem, in having a collar on the stem and in the absence of striations on the margin of the cap.

From the edible Reddish amanita, it is easily separated by the entire absence of any reddish hues or stains and of warts upon its cap.

From the Smooth lepiota its distinct, abrupt and marginal bulb at once distinguishes it.

A. ver´na Bull.—vernus, of spring. A variety of A. phalloides. POISONOUS. White. Pileus ovate then expanded, somewhat depressed, viscid, margin orbicular, even. Stem stuffed then hollow, equal, floccose, closely sheathed with the free border of the volva. Ring reflexed, swollen. Gills free. Pileus glabrous, even on the margin, white, viscid when moist. Gills white. Stem ringed, white, floccose, stuffed or hollow, closely sheathed at the base by the remains of the membranous volva, bulbous. Spores globose, 8µ broad.

In woods. Spring and summer.

The Vernal Amanita scarcely differs from white forms of the A. phalloides except in the more persistent and more closely sheathing remains of the wrapper at the base of the stem. It is probably only a variety of that species, as most mycologists now regard it, and it should be considered quite as dangerous. I have not found it earlier than in July, although in Europe it is said to appear in spring, as its name implies. Peck, 48th Rep. N.Y. State Bot.

Common over the United States. West Virginia, New Jersey, Pennsylvania, May to November. It appeared at Mt. Gretna, Pa., on May 28, 1899. McIlvaine.

The absence of a ring separates white forms of A. volvata and A. vaginata.

The virulence of its poison is the same as that of A. phalloides.

A. magnivela´ris Pk.—magnus, large; velum, veil. Pileus convex or nearly plane, glabrous, slightly viscid when moist, even on the margin, white or yellowish-white. Gills close, free, white. Stem long, nearly equal, glabrous, white, furnished with a large membranous white annulus, sheathed at the base by the appressed remains of the membranous volva, the bulbous base tapering downward and radicating. Spores broadly elliptical, 10×6–8µ.

Pileus 3–5 in. broad. Stem 5–7 in. long, 4–6 lines thick.

Solitary in woods. Port Jefferson, Suffolk county. July.

The species resembles Amanita verna, from which it is separated by its large persistent annulus, the elongated downwardly tapering bulb of its stem, and especially by its elliptical spores. Peck, 50th Rep. N.Y. State Bot.

I have not seen this species. Its resemblance to A. verna is enough to place the ban upon it until it has been tested.

A. map´pa Fr.—mappa, a napkin. From the volva. Pileus 2–3 in. broad, commonly white or becoming yellow, slightly fleshy, convexo-plane, obtuse or depressed, orbicular, dry, margin for the most part even. Stem 2–3 in. long, 3–5 lines thick, stuffed then hollow, almost equal above the bulb, rather smooth, white. Ring superior, soft, lax, here and there torn. Volva regularly circularly split, somewhat obliterated; the globoso-bulbous base united with the stem, with an acute and distant margin; the portion covering the pileus divided into broad, irregular, somewhat separating scales. Gills annexed, crowded, narrow, shining, white. Fries.

Odor stinking. The color is that of A. phalloides, with which A. virosa exactly agrees, more rarely straw color, lemon-yellow, becoming green.

In mixed woods. Frequent. Stevenson.

Spores spheroid, 7–10µ K.; 8–9×6–8µ B.; subglobose, 7–9µ diameter Massee.

New York woods and fields, common, September to October, Peck, 22d Rep.; North Carolina, Curtis; New England, Frost; Minnesota, Johnson; Ohio, Morgan; District Columbia, Miss Taylor.

POISONOUS.

Probably but a variety of A. phalloides.

A. spre´ta Pk.—spreta, hated. (Plate [VI], fig. 1, p. 6.) Pileus subovate, then convex or expanded, smooth or adorned with a few fragments of the volva, substriate on the margin, whitish or pale-brown. Gills close, reaching the stem, white. Stem equal, smooth, annulate, stuffed or hollow, whitish, finely striate at the top from the decurrent lines of the lamellæ, not bulbous at the base, but the volva rather large, loose, subochreate. Spores elliptical, generally with a single large nucleus, 10–13×6–8µ.

Plant 4–6 in. high. Pileus 3–5 in. broad. Stem 4–6 lines thick.

Ground in open places. Sandlake and Gansevoort. August. Peck, 32d Rep. N.Y. State Bot.

This is a dangerous species, because containing a deadly poison and resembling the most common forms of Amanitopsis, therefore likely to be mistaken for them. Specimens sent by me to Professor Peck were identified as his species. I add my own description.

Pileus oval, broadly umbonate, date-brown toward and on umbo, soft, dry, smooth, more or less sulcate on edge. Flesh white, thin, except at center. Stem tapers rapidly above ring and at base, white-reddish-brown toward middle, narrows toward volva from which it is almost free at the base, hollow, furfuraceous above ring. Gills white, crowded, free. Ring white, thin, persistent, but at times hard to distinguish because clinging to stem. Volva free, fitting close, upper margin thin, lower part quite thick, making stem appear bulbous, which it is not. White forms occur.

Not as virulent as A. phalloides, but like it in its POISONOUS effects. It differs from Amanitopsis in having a ring.

Grows in woods and on wood-margins.

Angora woods, West Philadelphia. On ground in mixed woods, open and grassy places in wood and wood-margins. August to September. McIlvaine.

A. recuti´ta Fr.—having a fresh or new skin. Pileus convex then plane, dry, smooth, frequently bearing fragments of the volva, margin nearly even. Stem stuffed then hollow, attenuated, silky, volva circumscissile, becoming obliterated, margin closely pressed to stem; ring distant, white. Gills striate-decurrent.

In pine woods. Common.

No report upon quality.

A. Cæsa´rea Scop.—king-like. (Called by the Greeks Cibus Deorum, food of the gods.) CAUTION. Pileus 3–8 in. across, hemispherical, then expanded, free from warts, distinctly striate on the margin, red or orange becoming yellow. Gills free, yellow. Stem 4–6 in. long, up to ¾ in. thick at base, slightly tapering upward, yellowish, flocculose, stuffed with white fibrils or hollow, with a conspicuous yellowish ring or veil. Volva white, large, distinct and membranous. Spores elliptical, 8–10µ Peck.

Open woods, under pines on lawns. July to October.

Reported from North Carolina, South Carolina, Massachusetts, Maryland, New Jersey, Ohio, Alabama, Louisiana, Pennsylvania, New York. Peck, Rep. 23, 32, 33, 48.

This emperor of fungi is the most showy of its race. It grows to 10 in. in height. The cap reaches 8 in. in diameter and the stem over 1½ in. in thickness. In very much smaller specimens about the same proportions occur. The cap is at first ovate, then hemispherical, then expanded. It has no warts or scales upon it. The margin is distinctly striate. The flesh is white, yellow or reddish under the skin; next to the gills it is usually yellow.

The stem tapers upward from the socket at its base. It is yellowish and covered with loose fibrils of darker hue. The ring is white, but frequently tinged with yellow. In taste and smell it is mild. Open woods is its favorite habitat, yet it is found growing luxuriantly under pines, maples, elms, on lawns. It is not often found, but when it is, it is solitary, or in groups or rings. In the latitude of Philadelphia it is found from July until October 1st. Further south its stay conforms to temperature, and it is more frequent. There is no doubt of its rare edibility abroad, and of its being eaten in America.

A specimen believed to be it should never be eaten until carefully distinguished from A. muscaria and A. Frostiana, which have warts or scales on the cap (which sometimes are not discernible after rain), white gills, and a volva which soon breaks up into fragments or scabs.

Appearing like a small form of A. muscaria, to which it was formerly referred, is A. Frostiana Pk. (Frost’s Agaric). It closely resembles small A. Cæsarea, especially in the yellow tinge of stem, ring and gills. The volva and ring (persistent in A. Cæsarea) soon disappear, but are traceable by fluffy fragments, or yellow stains. It is extremely poisonous.

The differences, concisely, are these: A. Cæsarea (Orange Amanita). Cap smooth, though occasionally with a few fragments of the volva as patches upon it. Gills yellow. Stem yellow. Volva usually persistent, sometimes breaking up into soft, fluffy masses.

A. muscaria (Fly Amanita). Poisonous. Cap covered with remains of the volva as scales or wart-like patches. Gills white. Stem white or light-yellow. Volva not persistent, breaking up into fluffy fragments or scales.
