 convex then expanded, obtusely-umbonate, at length usnally 

 upturned and split, very dry, even at first, then minutely 

 squamulose. grey ; gills broadly emarginate, ventricose,

Among moss, in pine woods, &c. 



Inodorous. Somewhat resembling T. saponaceum, but dis- 

 tinguished by the absence of smell. This same character, 

 and difference in colour separate the present from T. 

 sulphureum, with which it agrees in size and gUl structure.

 purplish- brown, blackish-umber, tan-colour, &c. ; gills 

 slightly sinuate, and more or less decurrent, rather distant, 

 yellowish tan-colour then pallid; stem about 2-3 in. long, 

 3-4 lines thick almost equal or slightly ventricose towards 

 the basci flocculose, coloured like the pileus, stuffed ; spores 

 subglobose, 4-5 /jl.
