84 TWENTY-THIRD REPORT ON THE STATE CABINET. 
with a dark reddish tinge; lamella uncinate, decurrent 
toothed, white, tinged with pink, the edge dark vinous-red ; 
stipe very slender, paler than the pileus, villous at the base, 
containing a reddish juice. 
Height 1'-1.5’, breadth of pileus 8’—4”. 
At the mossy base of trees. Greenbush. June. 
All my specimens have the pileus umbonate, and were 
cespitose, in which particulars they do not agree with pub- 
lished descriptions; still, I am unwilling to make a new 
species on such slight differences. 
50. AGARICUS CorTICOLA Schwim. 
_Pileus hemispherical or convex, subumbilicate, striate, 
brown, sometimes with a purplish tint, and sometimes having 
a grayish mealy appearance ; lamelle few, distant, subdecur- 
rent, and broadly attached to the stipe; stipe short, curved, 
stuffed or hollow, subconcolorous. 
About 6” high, pileus 2’-3” broad. 
Among moss and lichens, on trunks of elm trees. Albany. 
September. 
Subgenus — Omphalia. 
Stem cartilaginous. Gills truly decurrent.—Berk. Oui. 
The species of this subgenus are closely related to those of 
the preceding one, from which they differ chiefly in the decur- 
rent lamellee, which, though sometimes arcuate, are scarcely 
uncinate. The pileus is often umbilicate.
