134 THIRTY-EIGHTH REPORT ON THE STATE MUSEUM. 
much as in some species of Coprini, and in some species they are apt 
to become moist or almost deliquescent, especially in damp weather. 
Their color is generally white or yellowish-white when young, but they 
soon asssume the salmon hue of the spores. They generally yield these 
readily and in great abundance. The spores, in our species, are even, 
with a single exception, and generally subglobose or broadly elliptical. 
None of the species are very abundant with us and none are classed 
as edible.

Pileus fleshy, at first campanulate, then convex or expanded, even, 
glabrous, generally becoming fibrillose or slightly floccose-villose on the 
disk, occasionally rimose, variable in color; lamelle broad, somewhat 
ventricose, at first whitish, then flesh-colored; stem equal or slightly 
tapering upward, firm. solid, fibrillose or subglabrous, variable in color; 
spores broadly elliptical, .co025 to. 00032 in. long, .coo2 to .o0025 broad. 
Plant 2 to 6 inches high, pileus 2 to 4 broad, stem 3 to 6 lines thick. 
Decaying wood in groves, borders of woods and open places. 
This species, with us, is very common and very variable, yet it is not 
abundant. Usually but one or two specimens are found at atime, It 
grows especially on or about old stumps and prostrate trunks and may 
be found in wet weather from May to October. 
The typical form has the pileus and stem of a dingy or brown color and 
adorned with blackish fibrils, but specimens occur with the pileus white, 
yellowish, cinereous, grayish-brown or blackish-brown, I have never 
seen it of atruecervine color. It is sometimes quite glabrous and smooth 
to the touch and in wet weather it is even slightly viscid. It also occurs 
somewhat floccose-villose on the disk, and the disk, though usually plane 
or obtuse, is occasionally slightly prominent or subumbonate. The form 
with the surface of the pileus longitudinally rimose or chinky is probably
