STROPHARIA
flesh color becoming purplish black, close, moderately broad, edge white-
fimbriate. stipe short, 3/^-1 V2 in. long, Ys-Vi in. thick, equal, white, dry, floc-
culose above the annulus, fibrillose below, becoming smooth, stuffed to
hollow. ANNULUS membrauous, distant from apex, persistent, striate on upper
side. SPORES purple-brown, elHpsoid, smooth, 7-9 X 4.5-5 /x.
Gregarious to scattered on lawns or grassy places. Aug.-Oct.
This small species is not common but because of its occurrence on lawns
and the fact that it is suspected of being poisonous it has been included. It
might be mistaken for an Agaricus but the lamellae are not free from the stipe.

This species can be recognized by the large size, scaly stipe, and dull-
brown color, often with a smoky purpHsh tinge. It has been known under the
name Stropharia depilata (Pers. ex Fr.) Quel. It is one of the largest and most
conspicuous species of the genus. Although there does not seem to be any
definite information regarding its edibility, it is not recommended because
some of the Stropharia species are under suspicion as causing poisoning.
