usually uninucleate, .coo6-.00065 of an imch long, .0003~-.00034 
broad. ~ 
Pileus 3-6 lines broad; stem 1—1-5 inches long, about 1 line thick. — 
Damp ground in woods. Catskill mountains. July. 
The stunted entoloma has a peculiar starved or deformed appear- 
ance which is suggestive of the specific name. To the naked eye 
the pileus and stem appear to be clothed with minute scales, but 
under a good lens these are seen to be jointed matted filaments 
which seem to form a kind of tufted tomentum. In some speci- 
mens this tomentum is more dense than in others. 
Nolanidea 
Pileus thm, hygrophanous, subsilky when dry, often wavy and 
irregular. The hygrophanous pileus is the principal feature that 
distinguishes the species of this subgenus from the others.
