Tricholoma personatum Fr. 



Masked Tricholoma 



(Hym. Europ. p. 72. Syl. Fung., Vol. V. p. 130.) 



Pileus compact, becoming" soft, thick, convex or plane, obtuse, 

 regular, moist, glabrous, variable in color, generally pallid 

 or cinereous tinged with violet or lilac, the margin at first 

 involute and villose-pruinose, flesh whitish ; lamellae broad, crowded, 

 rounded behind, free, violaceous becoming sordid-whitish or fuscous; 

 stem generally thick, subbulbous, solid, fibrillose or villose-prui- 

 nose, whitish or colored like the pileus ; spores sordid-white, subel- 

 liptical, .0003 to .00035 in. long-, .00016 to .0002 broad. 



Pileus 2 to 5 in. broad ; stem 1 to 3 in. long, 6 to 12 lines thick. 



Woods and open places. Common. Albany, Rensselaer, Greene, 

 Delaware, Cattaraugus and Madison counties. September and 

 October. 



This species is quite variable in color, but easily recognized after 

 it is known. The pileus is rarely whitish or cinereous, but usually 

 it exhibits dull violaceous or dingy lilac or fuscous hues and the 

 lamellae are somewhat similar in color. The lamellae are separable 

 from the hymenophore and the species has for this reason sometimes 

 been placed in the genus Lepista. A form occurs in which the 

 stem is decidedly bulbous, and there is also a small form scarcely 

 attaining the dimensions given above. It grows either singly or in 

 troops, rarely in tufts. It is an edible species with tender and well- 

 flavored flesh. 



Tricholoma grave PJc. 



Heavy Tricholoma 



(N. Y. state Mus. Rep. 43, p. 17.) 



Pileus at first hemispherical, then convex, compact, glabrous, 

 grayish-tawny and somewhat spotted when moist, paler when dry, 

 the margin paler, irregular, involute, covered with a minute close 

 g-rayish-white tomentum or silkiness, flesh grayish-white ; lamellae 

 sub-distant, rounded behind or sinuate, adnexed, at first lohitish, 

 then pale-ochraceous or tawny; stem stout, compact, solid, sub- 

 squamulose, grayish-white, penetrating" the soil deeply ; spores 

 broadly elliptical, .0003 in long-, .0002 broad. 



Pileus 5 to 8 in. broad ; stem 4 in. long, i to 1.5 in. thick. 



Mixed woods. Suffolk county. September. 



This species is remarkable for its great si?e and weight. It is 

 apparently allied in this respect to T. Colossus, from which it is sep- 

 arated by the absence of any viscidity of the pileus, by the
