68 TWENTY-THIRD REPORT ON THE STATE CABINET. 
_ The genus Agaricus is a large one, and is divided, by the color 
of the spores, into five series, which are again divided into sub 
genera, distinguished by characters of minor importance. 
Series 1— LEucospPoRI. 
Spores white, rarely whitish or yellowish. 
Subgenus — Amanita. 
Veil universal, distinct from the cuticle of the pileus. 
Hymenophorum distinct from the stem.— Berk. Ouitl. 
Terrestrial species of moderate or large size, at first entirely 
enveloped in the volva, which is burst by the growing plant, a 
part being carried up by the pileus and forming evanescent 
patches or scattered, persistent, wart-like elevations upon its 
surface; the other part evanescent, or persistent, and attached 
to the base of the stem. The pileus at length becomes nearly 
horizontally expanded or slightly depressed, with the margin 
even or sulcate-striate. The stem is generally rather long, firm, 
fleshy and stuffed. The spores are subglobose. Most of the 
species are deemed poisonous.

1. AGARICUS CHSARIUS Scop. 
Pileus hemispherical, then expanded, striate on the mar- 
gin, naked, yellow; flesh yellow under the cuticle; lamelle 
free, yellow; stipe slightly tapering upward, annulate, 
sheathed at the base by the volva, stuffed. Utica. A. 8.

This is one of the few edible species of this subgenus. 
2. AGARICUS MUSCARIUS L. 
Pileus at first slightly viscid, hemispherical, then convex, 
expanded or even slightly depressed, substriate on the mar- 
gin, warty, rarely naked, red, yellow, or nearly white; flesh 
yellow under the separable cuticle; lamelle free, white ; 
stipe cylindrical or slightly tapering upward, annulate,
