In woods. 



Smell altogether peculiar, more soapy than nitrous (very 

 different to Ag. alcalinus, Hygrophorus murinaceus, &c. ; 

 always safely distinguished by the compact but not fragile 

 substance, distant gills, pileus with a dry cuticle, glabrous, 

 at length cracked into scales, flesh of pileus and stem 

 becoming reddish when wounded. Stem solid, 2-3 in. long, 

 ^ in. and more thick, often unequal or curved; base at- 

 tenuated, rooting, pallid ; sometimes glabrous, sometimes 

 squamulose when growing in leafy woods early in the season, 

 sometimes in late autumn elegantly reticulated with black 

 fibrils. Pileus fleshy, convex then plane, obtuse, 24 in. 

 broad, entirely glabrous, moist in rainy weather, but never 

 viscid, even, then when becoming dry more or less cracked 

 and rivulose, punctate, or broken up into scales ; normally 

 livid-brown, but varying to cinereous, greenish-olive, or 

 blackish ; margin thin, very glabrous, incurved at first. 

 Flesh whitish, becoming more or less red when cut. Gills 

 uncinately emarginate, distant, thin, quite entire, pallid- 

 white ; in a remarkable variety, yellowish. Scarcely any 

 other species is so much confused as the present, yet it is 

 easily distinguished by the soapy smell and the reddish 

 flesh. (Fries.) 



Tricholoma cartilagineum. Bull. 



Pileus 2 3 in. across, flesh rather thick, rigid, white ; 

 convex when young, obtuse, margin incurved and downy 

 then expanded and undulate or wavy, very obtuse, margin 

 arched, bent down, and persistently incurved ; always very 

 dry, densely covered with minute black granules on a white 

 ground ; gills emarginate and sinuate, crowded, thin, 2 lines 

 broad, white, then grey but not dingy; stem hollow, short 

 and firm, but fragile, 1-2 in. long, almost 1 in. thick, pure 

 white, surface even, glabrous, polished.
