Description of the Species. 
A. Growing on the ground or on rotten wood. 
I. Pileus viscid. 
THE STROPHARIA HIPILATA GROUP. 
Stropharia depilata, (Pers.) FIs. LXII and LXIJX 
Plants of this species are frequent in the northern woods in 
autumn. We have collected them near Lake Rosseau, Ontario, 
and on Keebish Island, Miich'. They grow on the ground and 
on rotten logs and stumps. The plants are good size with the 
pileus very glutinous in wet weather and the stem covered with 
white curly doccose scales. The photographs show the average 
size but much larger plants occur. 
Pileus thick and solid, convex to plane or broadly umbonate, 
obtuse, smooth, even on the margin, very glutinous in wet 
weather, brown or yellow cinnamon, margin appendiculate with 
bits of the veil when young. Lamellae adnate with decurrent. 
lines on the stem, broad, white, becoming purple black. Flesh 
whitish, solid. Stem solid, becoming hollow with age, equal, 
squarrose below the annulus with white floccose scales, floccose
