REPORT OF THE STATE BOTANIST 59 



Collybia abundans Pk. 

 Abundant Collybia. 



(Rep. 29, p. 38.) 



Pileus thin, convex or nearly plane, innately-fibrillose, subumbilicate, 

 whitish or pale grayish-brown, the disk often a little darker and more 

 densely fibrillose, the thin margin often splitting; lamellae rather narrow, 

 close, adnate, sometimes veiny, white; stem equal, glabrous, hollow, often 

 curved, easily splitting, colored like or a little paler than the pileus, 

 pruinose at the top; spores subglobose, .0002 to .00024 inch broad. 



Plant gregarious or somewhat csespitose; pileus i to 1.5 inch broad; 

 stem I to 2 inches long, about i line thick. 



Decaying wood and old trunks of trees, usually hemlock, in hilly and 

 mountainous regions. Catskill and Adirondack mountains. Also in 

 Rensselaer and Saratoga counties. August and September. 



This fungus does not occur frequently, but when it does occur it is 

 usually in great profusion. Large patches of it may sometimes be found 

 in warm wet weather covering the much decayed or mossy prostrate 

 trunks of trees in woods. The umbilicus of the pileus is very shallow or 

 entirely wanting. - When dried without pressure the margin of the pileus 

 rolls inward and hides the lamelliae, and the color becomes darker. In 

 dried specimens the pileus is often slightly and radiately rimose on its 

 surface, as in some species of Inocybe. The general character of the 

 pileus indicates a relationship to C. platyphylla. 



Collybia esculentoides Pk. 



Esculent-like Collybia. 

 (Rep. 39, p. 39.) 



Pileus thin, hemispherical or convex, umbilicate or centrally depressed, 

 glabrous, pale yellowish-brown, flesh white, taste bitter; lamellae broad, 

 subdistant, rather thick, adnexed or rounded behind, whitish; stem 

 slender, somewhat tough, glabrous, stuffed or hollow, colored like the 

 pileus; spores elliptical, .00025 ^^ .0003 inch long, .0002 broad. 



Pileus 6 to 12 lines broad; stem i to 2 inches long, i to 1.5 line thick. 



Ground in woods and open places. Albany county. September. 



Var. ochroleuca Pk. (Collybia ochroleuca, Rep. 46, p. 24.) 



This differs from the type in its paler and more ochraceous color and 

 in its farinaceous flavor. Woods. Ulster county. September. 



The species is related to the European C. esculetiia, from which it 

 differs essentially in the umbilicate pileus and in the absence of any 

 radicating base to the stem.
