REPORT OF THE STATE BO'ANIST 57 



This species is closely allied to the preceding one, from which it is 

 separated by its larger size, csspitose habit, different lamellae and shorter 

 spores. The fibrils of the pileus and stem have a finer and more tomen- 

 tose appearance, than those of the preceding species. They are con- 

 stantly tawny, while those of C. stipitaria are commonly grayish. As in 

 that species, the pileus often has a small papilla in the umbilicus and is 

 mostly concentrically sulcate or grooved when dry.

(Hym. Eur. p. 117. Syl. vol. v. p. 221.) 



Pileus a little fleshy, convex or nearly plane, glabrous, sometimes 

 slightly striate on the margin, whitish or pale reddish-brown; lamellae 

 adne.xed or free, narrow, rather close, white or whitish ; stem equal or 

 slightly tapering U[)ward,- hollow, reddish-brown, covered with a whitish 

 woolly down or tomentum; spores elliptical, .00024 ir^ch long, .00012 

 broad. 



Plant gregarious or somewhat csespitose ; pileus 1 to 2 inches broad; 

 stem I to 2 inches long, i to i 5 lines thick. 



Decaying wood and leaves in woods or open JDlaces. Long Island 

 and Catskill mountains. September. 



In our specimens the clothing of the stem is more dense and longer 



toward the base and thinner toward the top. The lamellae are not free, 



but almost adnate, and in this respect they appear to differ from the 



typical European plant. 



Laevipedes. 



Stem thin, hollow, equal, glabrous, (the base excepted) not conspicuously 

 striate. 



Smooth stemmed species having a tufted mode of growth and the pileus 

 hygrophanous have been transferred to a new^ tribe, Confertipedes; 

 species not caespitose have been placed in the tribe Tephrophanae if the 

 pileus is hygrophanous.
