REPORT OF THE STATE BOTANIST 67 



Pileus I to 2 inches broad; stem i to 1.5 inch long, about 2 lines thick. 



Among fallen pine leaves in woods. Cattaraugus county. September. 



The pileus becomes much paler upon losing its moisture. This dis- 

 appears from the disk first, the margin last. When fresh, the stem is 

 adorned with delicate flocci or fibrils, but these soon vanish or disappear 

 with a touch. 



Collybia atratoides Pk. 



Blackish Collybia. 



(Rep. 32, p. 27.) 



Pileus thin, convex, subumbilicate, glabrous, hygrophanous, blackish- 

 brown when moist, grayish-brown and shining when dry; lamellae rather 

 broad, subdistant, adnate, grayish-white, often transversely veiny above 

 and venosely connected ; stem equal, hollow, glabrous, grayish-brown 

 with a whitish mycelioid tomentum at the base; spores nearly globose, 

 about .0002 inch broad. 



Plant gregarious or subcsespitose; pileus 6 to 10 lines broad; stem 

 about I inch long, .5 to i line thick. 



Decaying wood and mossy sticks in woods. Saratoga county. August. 



The species is very closely allied to C. atrata and perhaps might be 



considered a mere variety of it. Its habitat, however, is different and the 



colors of the pileus and lamellae are not the same in both. The venose 



interspaces also seem to separate it from C. atrata. 



I 

 Collybia fuscolilacina Pk. 

 Lilac-brown Collybia. 

 (Rep. 39, p. 38.) 



Pileus thin, convex, glabrous, hygrophanous, even and brown when 

 moist, lilac-brown and rugose when dry; lamellae close, ventricose, ad- 

 nexed, brownish; stem slender, fiexuous, hollow, colored like the pileus, 

 mealy or pruinose at the top, with a whitish villosity at the base; spores 

 sul)globose or broadly elliptical, .00016 to .0002 inch long. 



Pileus 4 to 8 lines broad; stem 1.5 to 3 inches long, about i line thick. 



Among mosses and fallen leaves in open places in woods. Adirondack 

 mountains. August. 



This is apparently a rare species. It has been found but once.
