The whole plant is white or whitish, as in T. leucocephalum, from 

 which it is separated by its subdistant lamellae, somewhat umbo- 

 nate pileus and by the absence of any farinaceous odor.

(N. Y. state Mus. Rep, 38. p. 84.) 



Pileus thin, convex or nearly plane, slig-htly silky-fibrillose, whitish 

 with a brownish or g-rayish-brown slisfhtly prominent disk, taste and 

 odor strong, unpleasant; lamellae subdistant, emarginate, white: 

 stem equal, slightly silky, shining-, stuffed or holloiv, white; spores 

 subg-lobose or broadly elliptical, .00025 to .0003 in. lon^, .0002 to 

 •00025 broad. 



Pileus 10 to 15 lines broad ; stem 1 to 1.5 in. long, about 2 lines thick.

The species is related to T. inamoenum, from which it is separated 

 by its smaller size, less distant lamellae, stuffed or hollow stem and 

 different odor. Nor is the stem radicating or the disk tinged with 

 yellow as in that species. The odor is decidedly earthy, resembling 

 that of vegetable mold or mossy rocks. Its taste is similar to its 

 odor and remains in the mouth and throat a long time. 



Tricholoma lascivum Fr. 



Disgusting Tricholoma 



<Hym. Europ., p. 65, Syl. Fung., Vol. V., p. 112.) 



Pileus fleshy, convex or nearly plane, obtuse, at length somewhat 

 depressed, silky, then glabrous, even, whitish or pale tan color, the 

 margin at first involute, flesh white ; lamellae adnexed, thin, croioded, 

 white; stem solid, equal, rigid, rooting and tomentose at the hase, 

 fibrillose, white; spores .0003 to .0004 in. long, .00014 broad. 



Pileus 1 to 2 in. broad ; stem 2 in. long, 2 to 4 lines thick. 



Open places. Albany county, September. 



The European plant has the pileus pallid-tan color and has a
