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 ; lamellae 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, .00025 to. 00032 in. long, .0002 to .00025 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 a time 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 a true cervine 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
