Pholiota caperata, (Pers.). PI. XXIV. 
WRINKLED PHOLIOTA. 
A fine large species growing on the ground in woods and open 
places and mossy swamps, scattered or gregarious, frequent in 
this country and Europe. The specimens photographed were 
collected at Xeebish, Mich., in September. They show the aver¬ 
age size of the plants hut the variation is great. 
Pileus firm and fleshy, small for the size of the stem, ovate 
when young becoming broadly bell shaped and expanded, ob¬ 
tuse, glabrous, yellow or alutaceous, usually covered with white 
flocci especially when young. The fibers wash off in wet weather 
and the pileus becomes somewhat soggy. In the plants I have 
seen the pileus is deeply striate. Flesh whitish, thin toward 
the margin, mild. Lamellae moderately close, adnate or 
broadly notched, more or less uneven on the edge, whitish 
becoming rusty with spores. Stem solid or stuffed, equal, white, 
glabrous or floccose, remains of the universal veil sometimes 
suggesting a volva at the base. Annulus thick and white, near 
the middle of the stem. Spores elliptic, 7—'8x13—14^. 
Pholiota .. PL XXV. 
Two collections of these plants were made in Sept., 1910, one 
at Blue Mounds and the other at Devil’s Lake, Wis. They 
grew on the ground in thin woods. 
They differ from Pholiota caperata in the shorter, floccose 
stems, the small spores, the squamose pileus and the striate an¬ 
nulus. The annulus is exactly like that of Stropharia bila- 
mellata, Pk., and Dr. Peck to whom photographs and descrip¬ 
tions were submitted considered that the plants might belong to 
that species but recent collections of what seems to be true 
Stropharia bilamellata make the reference doubtful; the spores 
are very small and rusty browti, not purple brown, and the pile-
