Agarics
Our introductory description of the Amanita presents the most perfect botanical type of a large division of the fungus tribe, the Agaricaceæ, or gill-bearing mushrooms, one of the two great orders of fungi which include the large majority of edible species.
A brief consideration of the general classification of fungi will not be out of place at the head of this chapter.
CLASSIFICATION OF FUNGI
A fungus is a cellular cryptogamous (flowerless) plant, nourished through its spawn or mycelium in place of roots, living in air, and propagated by spores.
Fungi—mycetes—are naturally subdivided into two great divisions:
1. Sporifera—those in which the spores or reproductive bodies are naked or soon exposed, as shown in illustration on [page 79].
2. Sporidiifera—in which the spores are enveloped in sacs or asci. These resemble in shape the cystidium of illustration on [page 79].
The first of these divisions—the Sporifera, or naked-spored fungi—is again subdivided into four families, as follows:
