Our specimens of the above 

 species, which has been hitherto 



V\ j I I somewhat incompletely described, 



V^ ' ^ W are differing from the type esi)e- 



cially as to dimensions of the 

 spores (30 — 37// x 13 — 15« 

 against 30 /j X 10 y«). 



To judge from the descrip- 

 tion Pilocratera Ençileriana P. 

 Henn. is quite identical with 

 P. tricholoma as to the macroscopical appearance, and in microscopical 

 regards it is only differing by having the spores somewhat broader (14 — 1 7 yu) ; 

 by comparing, however, the form above diagnosed, which is found in the 

 middle of the American area of P. tricholoma and undoubtedly is to be 

 conferred to this species — it seems justified to suppose that also
