REPORT OF THE STATE BOTANIST I9OO I45 



Tricholoma nudum {BulL) Fr. 



Ground. Delhi. S. Sherwood. Westport. October. The spores 

 in our plant have a slight salmon tint, and tKe species might on this 

 account be referred to the genus Clitopilus, the lamellae being 

 adnate or slightly decurrent. 



Collybia ligniarius n. sp. 



Pileus thin, convex or nearly plane, obtuse or umbonate, glabrous, 

 striatulate on the very thin margin when moist, "even or obscurely and 

 somewhat irregularly striate when dry, whitish or isabelline, the center 

 often brownish; lamellae thin, rather narrow, commonly ventricose, 

 broadly excavated behind, subdistant, white ; stem equal, very rigid, 

 glabrous, hollow, whitish or pallid ; spores broadly elliptic or subglobose, 

 .0003-.00035 of an inch long, .00025-.0003 broad. 



Pileus 8-12 lines broad; stem 1-2 inches long, about i line thick. 



Old prostrate trunks and decaying wood of deciduous trees. North 

 Elba. July. The species is ambiguous between Collybia and 

 M y c e n a, but is referred to the former because the pileus is widely 

 expanded and its margin in the young plant is slightly incurved. 



Russula rugulosa n. sp. 

 Woods. Floodwood. August. Edible. For description of the 

 species see Edible fungi, p. 173. 



Russula abietina n. sp. 

 Under or near balsam fir and spruce trees. . North Elba. June and 

 July. Edible. For description of the species see Edible fungi, p. 173. 



Entoloma var labile n, sp. 



PLATE F, FIG. 17-27 



Pileus conical, ovate or subcampanulate, umbonate obtuse or some- 

 times slightly depressed or subumbiHcate at the apex, slightly fibrillose, 

 pale yellow when young, becoming reddish brown or burnt umber color 

 with age or reddish brown in the center and pale yellow on the margin; 

 lamellae moderately close, ascending, often eroded on the edge, broad 

 in front, white or whitish when young, pale salmon when mature ; stem 

 long, slender, equal, hollow, slightly fibrillose striate, whitish or pallid, 

 sometimes changing color like the pileus, frequently with a whitish 

 tomentum at the base; spores angular, uninucleate, .0004-.0005 of an 

 inch broad.
