170 Forty-fourth Report on the State Museum 



This plant might easily be mistaken for T. album, so close is the^ 

 resemblance between them, and yet it is quite distinct by its 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 laterarium Pk. 



SiDE-MABKED TeIOHOLOMA 

 (N, Y. State Mus. Rep., 26, p. 51.) 



Pileus convex or nearly plane, sometimes slightly depressed in 

 the center, pruinose, whitish, the dish often tinged ivith brick-red or 

 brown, the thin margin marked with slight, subdistant, short radia- 

 ting ridges, flesh white; lamellae narrow, crowded, emarginate, 

 decurrent in slight lines, white; stem nearly equal, solid, white; 

 spores globose, .00018 in. broad. 



Pileus 2 to 4 in. broad ; stem 2 to 3 in. long, 3 to 5 lines thick. 



Woods. Otsego and Oneida counties. June and July. 



It resembles some forms of T. album, but is separable by the 

 markings on the margin of the pileus and by its globose spores. 



Tricholoma leucocephalum, Fr. 



White-cap Teicholoma 



(Hym. Europ,, p. 71. Syl. Fung., Vol. v. p. 128.) 



Pileus fleshy, thin, tough, convex or plane, obtuse or obtusely 

 umbonate, even, moist, at first minutely silky, then glabrous, ivhite, 

 the margin spreading, naked, flesh white, odor farinaceous ; lamellae 

 thin, crowded, rounded behind, free, white; stem hollow, glabrous, 

 rooting at the narrowed solid base, subcartilaginous, white. 



Pileus 1 to 2.5 in. broad; stem 1 to 2 in. long; 2 to 4 lines thick. 



Pine groves. Green county. September. 



European authors do not agree in the dimensions ascribed to the 

 spores of this species. In Sylloge Fungorum they are said to be 

 .00036 to .0004 in. long, .00028 to .00032 broad, and according to 

 Lanzi they are .0002 to .00024 in. long, .00016 broad. In our plant 

 they are of the latter dimensions. 



Tricholoma fumidellum, Pk* 



Little-smoky Teicholoma 



(N. Y. State Mus. Rep. 26, p. 52.) 



Pileus convex, then expanded, subumbouate, glabrous, moist, 

 dingy-iuhite or clay-color clouded with broivn, the disk or umbo 

 generally smoky-brown ; lamellae crowded, subventricose, whitish ;
