adnexed, white ; stem equal, stuffed or hollow, silky-fibrillose, white; 

 spores broadly elliptical or subglobose, .00025 to .0003 in. long, .0002 

 to .00025 broad. 



Pileus 1.5 to 3 in. broad ; stem 2 to 4 in. long, 3-6 lines thick. 



Woods and groves. North Elba. Sept. 



The species is perhaps too closely related to T. virgatum, but it is 

 separable by its prominent subacute umbo, paler pileus, hollow stem 

 and hot or peppery taste. The cuticle is separable from the pileus. 



Tricholoma silvaticum, n. sp. 



[Plate 2. Figs. 16-19.] 



Pileus convex or nearly plane, dry, glabrous, subumbonate, whitish; 

 lamellae broad, ventricose, subdistant, adnexed, white ; stem subequal, 

 solid, white ; spores rather large, elliptical, .00045 to .0005 in. long, 

 .0003 broad. 



Pileus 1 to 1.5 in. broad ; stem 1 to 2 in. long, 2 to 4 lines thick. 

 Mossy ground in woods. North Elba. Sept. The whole plant is 

 white and is related to T. leucocephalum, from which it is separated by 

 its subdistant lamellae, somewhat umbonate pileus and by the absence 

 of any farinaceous odor. From T. inamcenum it is distinguished by 

 the absence of odor and stem not radicated. 



Tricholoma nobile, n. sp. 



Pileus fleshy, convex or nearly plane, dry, minutely punctate or 

 squamulose with innate fibrils, whitish or slightly tinged with yellow, 

 flesh white, taste unpleasant, lamellse broad, rather close, rounded 

 behind and slightly adnexed, white, slowly changing to pale-yellow 

 where wounded; stem equal, solid, slightly floccose-pruinose, whitish; 

 spores minute, subglobose, .00016 to .0002 in. broad. 



Pileus 2 to 4 in. broad; stem 1.5 to 2.5 in. long. 4 to 8 lines thick. 



Woods. North Elba. Sept. 



The plant is closely related to T. album, for which it might easily be 

 mistaken, but its habit is more clearly that of other species of Tri- 

 choloma, and it may be distinguished by the minute though rather 

 obscure squamules, the insertion of the lamellae and the subglobose 

 spores. Its taste is very unpleasant and leaves a burning sensation 

 in the mouth and throat for a long time. 



Tricholoma brevipes, Bull. 

 Menands, Albany county. Oct. A small form but apparently not 

 distinct.
