Student's Hand-book of Mushrooms of America, Edible and Poisonous

In Plate A is presented a sketch of the common field mushroom, Agaricus campester. Fig. 1 represents the mature plant; Fig. 2, a sectional view of the same; Fig. 3, the basidia, club-shaped cells from the summit of which proceed the slender tubes called sterigmata, which support the spores—highly magnified; Fig. 4, the sterigmata; Fig. 5, the mycelium, highly magnified, supporting immature mushrooms; Fig. 6, the spores as shed from an inverted mushroom cap; Fig. 7, spores magnified.

INTRODUCTION.

In the year 1876, as Microscopist of the Department of Agriculture, I prepared, as a part of the exhibit of my Division at the Centennial Exhibition at Philadelphia, a large collection of water-color drawings representing leading types of the edible and poisonous mushrooms of the United States, together with representations of about nine hundred species of microscopic fungi detrimental to vegetation.

In the preparation of the first collection I had the valuable assistance of Prof. Charles H. Peck, State Botanist of New York, and in the second the hearty co-operation of Rev. M. J. Berkeley and Dr. M. C. Cook, the eminent British mycologists.

The popular character of this exhibit attracted the attention of the general public, and many letters were received at the Department showing an awakening interest in the study of fungi, particularly with regard to the mushroom family, as to methods of cultivation, the means of determining the good from the unwholesome varieties, etc.

My first published paper on the subject of edible mushrooms, entitled "Twelve Edible Mushrooms of the U. S.," appeared in the annual report of the Department of Agriculture for 1885. This was followed by others to the number of five, and as the demand for these reports increased, reprints were made and issued, by order of the Secretary of Agriculture, in pamphlet form, under the general title of "Food Products." Numerous editions of these reprints were issued by the Department up to 1894. During the year 1894, and the first half of 1895, 36,600 of these reports were sent out by the Department, and the supply was exhausted. They have been out of print for more than two years. It is in view of this fact, and in response to a great and constant demand for these publications, that I have undertaken to publish a series of five pamphlets on the edible and poisonous mushrooms of the United States, which shall embody the substance of the five pamphlets on "Food Products" above alluded to, supplemented by new matter relating to classification, general and specific, analytical tables of standard authors, and a continuation of the chapters on structure, etc. Additional plates, representing leading types of edible and poisonous mushrooms, will also be inserted in each number.

In the compilation and extension of this work I have the assistance of my daughter, Miss A. Robena Taylor, who has given considerable attention to the study of fungi, and who has been my faithful coadjutor in the work of collecting specimens, etc., for a number of years.

For valuable suggestions as to structural characteristics and methods of classification I am especially indebted to Prof. Chas. H. Peck, of Albany, New York, Dr. M. C. Cooke, of England, and Prof. P. A. Saccardo, of Italy.

The colored plates in pamphlet No. 1, together with a few of those which will appear in the succeeding numbers of this series, are reproductions of those prepared, under my direct supervision, for the pamphlets entitled "Food Products" published by the Department of Agriculture and referred to above.

CRYPTOGAMS.

The cryptogamic or flowerless plants, i. e., those having neither stamens nor pistils, and which are propagated by spores, are divided, according to Dr. Hooper, into the following four classes:—Pteridophyta or vascular acrogens, represented by the ferns, club-mosses, etc.; Bryophyta or cellular acrogens, represented by the musci, scale-mosses, etc.; AlgÆ, represented by the "Red Seaweeds," DiatomacÆ, etc.; Fungi or Amphigens, which include the molds, mildews, mushrooms, etc. The lichens, according to the "Schwendener Hypotheses," consist of ascigerous fungi parasitic on algÆ.
