In this pamphlet we have to deal only with part of the first class.The Basidiomycetes can in turn be divided into two very natural classes, 1st, the Hymenomycetes, those that have the spores exposed and free from the beginning, or at least from a very early state- 2nd, the Gastromycetes, those that develop the spores in cavities or chambers within the tissue of the plant. We are aware that these divisions are not in keeping with the very latest authorities which primarily divide the Basidiomycetes into sections based respectively on septate or nonseptate basidia, but we believe that these latter divisions while possibly theoretically correct, tend only to confuse matters excepting to the advanced and expert student.It should not be inferred from the above that in order to recognize the Gastromycetes it is necessary to study the nature of the basidia, or make other minute anatomical examination. As a matter of fact, the merest tyro soon learns to recognize on sight the various phalloids, bird-nest fungi, and various kinds of puff-balls constituting the Gastromycetes and they were well classified before their anatomical structures were known.Terms used in the description of the Gastromycetes.Peridium.The shell or hull, enclosing the spore mass of a gastromyces is called the peridium. It varies in the different genera, the simplest type is a simple, uniform layer such as surrounds the spore mass in the accompanying cut of Scleroderma. (Fig. 2.) Usually however, the peridium consists of two distinct layers, called the outer peridium or exoperidium and the inner peridium or endoperidium. In Geaster, the outer peridium is thick and when the plant ripens it splits in a stellate manner separating from the inner peridium and becoming more or less reflexed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
