TRICHOLOMA. 193 



Tricholoma immundus. Berk. 



Pilens 2-3 in. across, rather fleshy at the disc, becoming 

 very thin towards the inflexed margin, minutely silky or 

 with very small scattered squamules visible only under a 

 lens, when dry dingy white, with darker stains; gills very 

 slightly rounded behind, rather close, about 1^ lines broad, 

 pale grey with a pink tinge, in the larger specimens more 

 especially becoming very dark with age, margin entiro ; 

 stem about 2 in. long, 2 lines thick, nearly equal, dingy 

 white, fibrillose, often broken up into squamules at the apex, 

 solid ; spores subglobose, apiculate, colourless, 4-5 //. 

 diameter; every part of the fungus becomes blackish when 

 bruised.

 Hdbk., p. 31 ; Cke., Illustr., pi. 61 (not characteristic). 



Among short grass in open places. 



Caespitose or solitary ; characterised by the very dark 

 gills and thin pileus. The gills separate readily from the 

 pileus during drying, a character taken along with the 

 globose spores, that suggests the genus Paxillus. 



Tricholoma inodermeum. Fr. 



Pileus 1-2 in. across, flesh rather thin, white, then tinged 

 red ; conico-campanulate, acute, then becoming more convex 

 and somewhat umbonate, the surface becoming broken up 

 into fibrils and adpressed, radiating scales, rufous-brown; 

 gills free or slightly adnexed, very broad and remarkably 

 ventricose, almost semicircular, distant, rather thick, per- 

 sistently white, but becoming spotted with reddish when 

 bruised ; stem about 3 in. long, l|-2 in. thick, equal, hardly 

 fibrillose, white with a rufous tinge, apex powdered with, 

 white, stuffed, hollow upwards, entirely fibrous, tough ; 

 spores elliptical, 7-8 x 4 p..

In damp, dense pine woods, &c. 



Not closely allied to any known species. Resembling 

 Inocybe pyriodora in habit.
