NATURAL HISTORY SURVEY 33 



Woods, Millers, Ind., October, 1902. A. S. Bertolet. Mr. 

 Bertolet notes that the farinaceous odor and taste attributed to 

 the species, are not noticeable in the plants collected by him. 

 Tricholoma decorosum Pk. 



Pileus firm, hemispherical then convex or nearly plane, 

 adorned with numerous brownish subsquarrose tomentose scales, 

 dull ochraceous or tawny: flesh white. 



Lamellae close, rounded and slightly emarginate behind, the 

 subcrenulate. 



Stem solid, equal or slightly tapering upward, white and 

 smooth at the top, elsewhere tomentose-squamulose, colored like 

 the pileus. 



Spores broadly elliptical, 5 x 4 /u,. Pileus 2.5 to 5 cm. broad; 

 stem 5 to 10 cm. long, 4 to 8 mm. thick. Decaying trunks of 

 trees. 



Woods, Glencoe. October, 1902. Harper and Bertolet. 

 Tricholoma album Schaeff. 



Pileus fleshy, tough, convex, becoming plane or depressed, 

 obtuse, very dry, even, glabrous, white, sometimes yellowish on 

 the disk, rarely wholly yellowish, the margin at first involute; 

 flesh white, taste acrid or bitter. 



Lamellae emarginate, somewhat crowded, distinct, white. 



Stem solid, elastic, equal or tapering upwards, externally 

 fibrous, obsoletely pruinose at the apex, white. 



Spores ellipsoid, 5 to 6 /*. long. 



Pine barrens at the head of Lake Michigan, Calumet Heights, 

 Ind. August, 1899. Pileus o to 10 cm. broad; stem 5 to 10 cm. 

 long, 8 to 12 mm. thick. Also collected in woods at Wmfield. 

 Pileus uneven in outline, margin sometimes irregularly waved in 

 large specimens. 

 Tricholoma personatum Fr. 



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- 

 pruinose, whitish or colored like the pileus. 



Spores sordid white, subellipsoid, 7.5 to 9 x 4 to 5 /*. Pileus 

 5 to 12.5 cm. broad; stem 2.5 to 7.5 cm. long, 12 to 25 mm. thick. 



On the ground in woods, Glencoe. October. The stem in 

 our plant can scarcely be called " subbulbous." It is enlarged 

 downward into a broad truncate base. The spores are creamy- 

 white, 6 to 7 x 3 to 4 /x. 



Among dead leaves in woods. Glen Ellyn. September. 

 These plants are unicolorous, varying from a beautiful heliotrope 

 to whitish-livid. 



Prof. Peck suggests (Rep. X. Y. Mus. 54: 165), that this species 

 is probably identical with his Entoloma grareolens.
