REPORT OF THE BOTANTST. 99 
96. AGARICUS PERPLEXUS 7%. Sp. 
Pileus fleshy, convex, then expanded, often broadly subum- 
bonate, smooth, yellow, the disk red or brownish-red, the 
margin paler; lamelle not broad, rounded at the inner 
extremity, easily separating from the stipe, pale yellow, then 
greenish-tinged, finally purple-brown; stipe subequal, firm, 
slightly fibrillose, hollow, yellow, reddish at the base; flesh 
white ; spores purplish-brown. . 
Height 2’— 3’, breadth of pileus 2’—3’, stipe 2’’-3” thick. 
About stumps in woods or open places. Common. Sand- 
lake, Albany and Catskill Mountains. September and October. 
The plant has a mild taste and no marked odor. It grows 
singly or in dense tufts. It is closely related to A. sublateri- 
tius, A. epixanthus and A. fascicularis, but as it does not 
agree with the description of either of them, I have no alterna- 
tive but to describe it as a new species. 
97. AGARICUS VELUTINUS Pers. 
Pileus fleshy, thin, convex or expanded, brittle, minutely 
tomentose-scaly, becoming smooth, hygrophanous, yellow 
with the disk reddish ; lamelle rather broad, attached, tapering 
toward the outer extiemity, dark brown tinged with red, the 
edge whitish-beaded; stipe equal, rather slender, hollow, 
fibrillose, subconcolorous, white-mealy and slightly striate at 
the top; spores black. 
Height about 2’, breadth of pileus 11.5’. 
Roadsides. Albany Cemetery. September. The pileus 
sometimes cracks transversely. 
/” Subgenus— Psilocybe. 
Veil, if present, not forming a ring. Margin of pileus at first 
incarved.—Berk. Outt. 
The species of this subgenus are smaller, and have the pileus 
thinner than those preceding.
