190 FUNGUS-FLORA. 



closely crowded, snow-white ; stem 2-3 in. long, J in. thick, 

 about equal, white, mealy, solid. 



Agaricus guttatus, Schaeffer, t. 240; Cke., Hdbk., p. 29 ; Cke., 

 Illustr., pi. 59? 



Burders of woods, &c. 



Sometimes rather tufted. Differs from T. tigrimum in the 

 persistently white gills and the sulcate margin of the pileus. 

 Cooke's figures differs from the form described above in the 

 smaller size, and in the pileus being ornamented with large, 

 innate, dark brown patches, more or less concentrically 

 arranged, and disappearing towards the margin. 



Tricholoma columbetta. Fr. 



Entirely pure white but here and there spotted with 

 red. Pileus 2-4 in. across, flesh firm but not thick, convex 

 then expanded, obtuse, wavy, dry, glabrous at first, then 

 squamulose or cracked into squarrose particles, margin 

 downy and incurved when young ; gills slightly emarginate, 

 almost free, 2-3 lines broad, persistently clear white; stem 

 3-4 in. long, almost 1 in. thick in large forms, usually 

 unequal, at times quite short, solid; spores elliptical, 

 6-7 X 4-5 p..

In woods. 



Widely separated from every other species of Tricholoma. 

 Solitary, inodorous; taste mild. The following are re- 

 markable forms : 



(A.) In heathy birch woocts among moss. Stem short, 

 stout, somewhat rooting, moist, naked, not distinctly striate ; 

 pileus always wavy and more or less lobed, moist in damp 

 weather, usually spotted with red, margin involute and 

 downy : 



(B.) In damp bushy places. Stem elongated, base 

 narrowest, pileus wavy, silkily-fibrillose, somewhat squamu- 

 lose, sometimes with brownish spots : 



(0.) In very shady beech woods. Pure white, not spotted, 

 but there are sometimes bluish spots in the flesh; stem 

 equal, cylindrical, 4 in. long, f in. thick, fibrillosely striate; 

 pileus regular, flattened, obtuse, 4 in. across, evidently 

 fibrillose when dry, margin naked, flesh thin, splitting.
