Agaricas (Tricliolomd) immundus, Berk., Outl., p. 103 ; Cke., 

 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.

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

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

 a,nd 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, stufl'ed, hollow upwards, entirely fibrous, tough ;
