TRICHOLOMA. 203 



Tricholoma opicum. Fr. 



Pileus 1-1^ in. across, flesh rather thin, becoming greyish ; 

 convex then expanded, obtusely-umbonate, at length usually 

 upturned and split, very dry, even at first, then minutely 

 squamulose. grey ; gills broadly emarginate, ventricose, 

 rather thick, scarcely distant, hoary ; stem 23 in. long, 

 2-3 lines thick, equal, fibrillose, becoming almost glabrous, 

 pallid then greyish, stuffed. 



Agaricus (Tricholoma) opicus, Fries, Epicr., p. 39. 



Among moss, in pine woods, &c. 



Inodorous. Somewhat resembling T. saponaceum, but dis- 

 tinguished by the absence of smell. This same character, 

 and difference in colour separate the present from T. 

 sulphureum, with which it agrees in size and gill structure. 



Tricholoma bufonium. Pers. 



Pileus 1^-21 in. across, flesh thick ; convex then expanded 

 or almost plane, somewhat umbonate or gibbous, silky at 

 first, soon almost glabrous, punctately rugose, opaque, 

 purplish- brown, blackish-umber, tan-colour, &c. ; gills 

 slightly sinuate, and more or less decurrent, rather distant, 

 yellowish tan-colour then pallid ; stem about 2-3 in. long, 

 3-4 lines thick almost equal or slightly ventricose towards 

 the base, flocculose, coloured like the pileus, stuffed ; spores 

 subglobose, 4-5 //,.

In pine woods. 



Distinguished by the tan-coloured gills and flocculose or 

 downy stem. 



Tricholoma lascivum. Fr. 



Pileus about 2 in. across, flesh rather thin, persistently 

 white ; convex then plane, at length depressed, obtuse, 

 indistinctly silky, dry, tan-colour becoming pallid ; margin 

 at first incurved ; gills arcuately adnexed, at length arcu- 

 iitely decurrent, horizontal, thin and crowded ; stem about 

 2 in. long, solid, rigid, entirely fibrous, equal, externally 

 fibrillose, whitish, apex with white meal, base rooting and 

 downy; spores 8-10 x 4-5 p.
