CLASSIFICATION i8i 



Somewhat resembling Tricholoma nudum, but distinct in tlie 

 decurrent gills. 



In woods, etc. 



var. pengelleyi. — Differs from the typical form, more especially 

 in having the stem narrowed at the base. The abrupt white apex 

 of the stem is also remarkable in this variety. 



C. opiparia. — Cap fleshy, plane, obtuse, even, smooth, shining, 

 yellowish red, 2-4 in. across ; gills slightly decurrent, crowded, 

 whitish ; stem more or less equal, whitish, solid, 2-3 in. long. 



Smell not remarkable, taste pleasant. Cap rosy flesh-colour or 

 fleshy tan-colour. 



Among moss under trees, etc. 



C. amara. — Taste very bitter. Cap fleshy at the disc, convex, 

 then plane, obtuse, or sometimes slightly umbonate, dry, rufescent 

 or yellowish tawny, slightly flocculose, ii-2| in. across ; gills 

 slightly decurrent, crowded, white ; stem tough, white, floccose, 

 then almost smooth, solid, about 2 in. long. 



A very distinct species, but the variable colour of the cap is liable 

 to be misleading. Known without fail by the very bitter taste, along 

 with its other characters. 



On the ground under trees, etc. 



C. socialis. — Cap fleshy at the disc, convex, soon expanded, 

 rather acutely umbonate when young, usually obtuse with age, 

 smooth, pale yellowish red or almost flesh-colour, about i in. across ; 

 gills very slightly decurrent, scarcely crowded, becoming yellowisli ; 

 stem often slightly curved, smooth, solid, reddish, about i in. long. 



Base of stem thickened and rooting, as in Marasniius peronatiis ; 

 it is also very strigose. 



C. vernicosus differs in the stuffed, yellowish stem, cap never 

 umbonate, and bright yellow gills. 



On heaps of fallen pine leaves. 



*** Cap becoming yellowish. 



C. amarclla. — Smell strong, taste very bitter. Cap firm, some- 

 what umbonate, smooth, even, reddish yellow or pale fawn-colour, 

 about 2 in. across ; gills slightly decurrent, crowded, forked, pallid 

 with a gre}^ tinge, somewhat shining ; stem equal, tough, base 

 with white down, solid, about 2 in. long. 



Taste very bitter ; smell resembling prussic acid. 



Among grass. 



C. vernicosa. — Cap rather fleshy, convex, then expanded, de- 

 pressed when old, even, smooth, deep shining yellow, edge incurved, 

 2-3 in. across ; gills slightly decurrent, narrowed behind, rather 

 distant, yellow ; stem equal, even, smooth, yellow, about i in. long. 



Superficially resembling Tricholoma cerimim, but easily dis- 

 tinguislied by the gihs being truly decurrent and not sinuate behind. 



In larch woods, etc.
