Three New British Coprini. A. H.R. Buller. 365 



The distinguishing characters of this species he in the foxy- 

 red colour of the very young pileus, the minute reddish or 

 whitish scales which remain on the expanded pileus inter- 

 spersed with clavate hairs, the finally depressed disc, the deep 

 black spores and the absence of cystidia on the sides of the 

 gills. The pileus, when expanded, reminds one of that of Co- 

 prinus plicatilis. Sometimes very minute or dwarf fruit-bodies 

 are to be found along with similar dwarfs of C. lagopus in cre- 

 vices in old horse dung masses. The fungus is common on horse 

 dung cultures at Winnipeg.
