usually uninucleate, .0006-.00065 of an inch long, .0003-.00034 

 broad. 



Pileus 3-6 lines broad; stem 1-1.5 inches long, about i 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 tomenlum. In some speci- 

 mens this tomentum is more dense than in others. 



Nolanidea 



Pileus thin, 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.
