Caution at the threshold
While, then, from the point of view of desired popularity of my book, the grim greeting of a death's-head upon the frontispiece might be considered as something of a handicap, the author confesses that this attitude is the result of "malice prepense" and deliberation, realizing that he is not offering to the "lay public," for mere intellectual profit, this scientific analysis of certain fungus species. Were this alone the raison d'être or the logical outcome of the work—mere identification of edible and poisonous species—the grewsome symbol which is so conspicuous on two of my pages might have been spared. But when it is remembered that with the selected list of esculent mushrooms herein offered is implied also an invitation and a recommendation to the feast thereof, with the author as the host—that the digestive functions of his confiding friends or guests are to be made the final arbiters of the correctness of his botanical identification—the ban of bane may as well be pronounced at the threshold. Let the too eager epicurean be "scared to death at the outset," on the general principle pro bono publico, and to the conciliation of the author's conscience.
To correspondents
The oft-repeated queries of other correspondents suggest the wisdom of a clearer definition of the limitations of the present work. Several individuals have written in surprise of their discovery of a new toadstool which I "did not include in my pictured magazine list," with accompaniment of more or less inadequate description and somewhat enigmatical sketches, and desiring the name of the species and judgment upon its esculent qualities. Such correspondence is a pleasing tribute to an author, and is herewith gratefully acknowledged as to the past and, with some mental reservations, welcomed as to the future. The number of these communications—occasionally several in a day, and with consequent rapid accumulation—renders it absolutely impossible for a busy man to give them the prompt personal attention which courtesy would dictate. My "mushroom" pigeon-hole, therefore, is still plethoric with the unhonored correspondence of many weeks; and inasmuch as the continual accession more than balances the number of my responses, a fulfilment of my obligations in this direction seems hopeless in contemplation. I would therefore beg the indulgence of such of my friends as have awaited in vain for my reply to their kind communications, even though the future should bring no tidings from me. All of these letters have been received, and are herewith acknowledged: many of them, too, if I may be pardoned what would seem to be a most ungracious comment, for which the "dead-letter" office would have been the more appropriate destination.
Consider the recipient
I refer to the correspondence "with accompanying specimens," the letter occasionally enclosed in the same box with the said specimens, which, upon its arrival, arouses a protest from the local postal authorities, and calls for a liberal use of disinfectants—a disreputable-looking parcel, which, indeed, would appear more consistently referable to the health-board than to the mycologist. So frequent did this embarrassing episode become that it finally necessitated the establishment of a morgue for the benefit of my mushroom correspondents, or rather for their "specimens," usually accompanied with the queries, "What is the name of this mushroom? Is it edible?" I have been obliged to write to several of my friends that identification of the remains was impossible, that the remnant was more interesting entomologically than botanically, and begging that in the future all such similar tokens shall be forwarded in alcohol or packed in ice.
Rapid decay
"First impressions are lasting" and "a word to the wise is sufficient." I would suggest that correspondents hereafter consider the hazard of an introduction under such questionable auspices. Most species of mushrooms are extremely perishable, and their "animal" character, chemically considered, and their tendency to rapid decomposition, render them unfit for transportation for any distance, unless hermetically sealed, or their decay otherwise anticipated.
In the possibility of a continuance of this correspondence, consequent upon the publication of this present book, the writer, in order to forefend a presumably generous proportion of such correspondence, would here emphasize the fact that he is by no means the authority on mycology, or the science of fungi, which the attitude of his inquiring friends would imply. Indeed, his knowledge of species is quite limited. An early fascination, it is true, was humored with considerable zeal to the accumulation of a portfolio of water-colors and other drawings of various fungi—microscopic, curious, edible, and poisonous—and this collection has been subsequently added to at intervals during his regular professional work.
More than one of the originals of the accompanying colored plates have been hidden in this portfolio for over twenty years, and a larger number for ten or fifteen years, awaiting the further accumulation of that knowledge and experience, especially with reference to the edibility of species, which should warrant the utterance of the long-contemplated book.
Number of mushroom species
The reader will therefore kindly remember that out of the approximate 1000 odd species of fungi entitled by their dimensions to the dignity of "toadstools" or "mushrooms"—after separating the 2000 moulds, mildews, rusts, smuts, blights, yeasts, "mother," and other microscopic species—and out of the 150 recommended edible species, the present work includes only about thirty. This selection has direct reference to popular utility, only such species having been included as offer some striking or other individual peculiarity by which they may be simply identified, even without so-called scientific knowledge.
The addition of color to the present list enables its extension somewhat beyond the scope of a series printed only in black and white, as in the distinction of mere form alone an uncolored drawing of a certain species might serve to the popular eye as a common portrait of a number of allied species, possibly including a poisonous variety.
Mycology and mycophagy
Need of a practical work
While the study of "fungi" has a host of devotees, the mysteries which involve the origin of life in this great order of the cryptogamia having had fascinating attractions to microscopical students and specialists, the study of economic mycology has been almost without a champion in the United States. Thus we have many learned treatises on the nature, structure, and habits of fungi—vegetative methods, chemical constituents, specific characters, classification—learned dissertations on the microscopical moulds, mildews, rusts and smuts, blights and ferments, to say nothing of the medico-scientific and awe-inspiring potentialities of the sensational microbe, bacterium, bacillus, etc., which are daily bringing humanity within their spell and revolutionizing the science of medicine. But among all the various mycological publications we look in vain for the great desideratum of the practical hand-book on the economic fungus—the mushroom as food! The mycologist who has been courageous enough to submit his chemical analysis and his botanical knowledge of fungi to the test of esculence in his own being is a rara avis among them; indeed, a well-known authority states that "one may number on the fingers of his two hands the entire list of mycophagists in the United States." The absence of such works upon the mushroom and "toadstool," greatly desired for reference at an early period of my career, and little better supplied to-day, led to a resolve of which this volume is but an imperfect fulfilment.
Limitations of this volume
The special character of my volume, then—the collateral consideration of the fungus as food—will be sufficient excuse for the omission of a merely technical discourse upon the structure, classification, and vegetation of fungi as a class—a field so fully covered by other authors more competent to discuss these lines of special science, and to a selection of whose works the reader is referred in the list herewith appended, to a number of which I am indebted for occasional quotations. A general idea of the methods of dissemination and habitats of fungi will be found in the final chapter on "spore-prints," while under the discussion of the "Amanita," Agaricus campestris, and the "Fairy Ring" the reader is referred to a condensed account of the methods of vegetation and growth of fungi sufficient for present purposes. Other references of similar character will be noted under "Fungi," in Index.
