Tricholoma Columbetta Fr. 



Dove-colored Teicholoma 



(Hym. Europ., p. 55. Syl. Fung., Vol. V, p. 99.) 



Pileus convex, thea nearly plane, fleshy, obtuse, rigid, somewhat 

 flexuone, dry, at first glabrous, then silky -fihrillose, becoming even or 

 squamulose, white, the margin at first involute, more or less tomen- 

 tose, flesh white, taste mild ; lamellae close, emarginate, thin, white ; 

 stem stout, solid, unequal, nearly glabrous, white ; spores, .00028 to 

 .0003 in. long, .00016 to .0002 broad. 



The species is very variable and the following varieties have been 

 described. 



Var. A. Pileus nearly always repand or lobed, at first glabrous, 

 even, at length rimose-squamose, often reddish-spotted, the margin 

 when young inflexed, tomentose ; stem obese, even, unequal, swollen, 

 an inch thick. The typical form. 



Birch woods among mosses. 



Var. B. Pileus subflexuous, silky-fibrillose, at length squamulose, 

 sometimes fuscous-spotted, the margin scarcely tomentose; stem 

 longer, equal or slightly narrowed at the base. 



Bushy places. Intermediate between A. & 0. • 



Var. C. Pileus regular, flattened, evidently fibrillose, sometimes 

 spotted with blue, four inches broad; stem equal, cylindrical, 

 fibrillose-striate, four inches long. 



Beech woods. A showy variety so diverse from variety A that it 

 might be regarded as a distinct species, did not variety B connect 

 them and so much resemble both that it might with equal propriety 

 be referred to either. 



Pileus 2 to 4 in. broad ; stem 1 to 4 in. long, 3 to 12 lines thick. 



Woods and pastures. Albany county. 



It may be distinguished from T. album by its mild taste. It is 



recorded as edible.

Grand Tricholoma 



(N. Y. state Mus. Rep., 44, p. 128.) 



Pileus thick, firm, hemispherical, becoming convex, often irregular, 

 dry, squamulose, somewhat silky-fibrillose toward the margin, tuhite, 

 the margin at first involute, flesh grayish-white, taste farinaceous ; 

 lamellse close, rounded behind, adnexed, white ; stem stout, solid, 

 fibrillose, at first tapering upward, then equal or but slightly thick-
