N.E — Scarboro'. Parasitic on Russula nigricans. 



S.W.— Edlington Wood (F.F., '91, W. White). 



The mealy appearance of the pileus is due to the presence 

 of myriads of large spinulose spores, which were at one time 

 considered as the spores of a parasitic mould called asterophora. 

 These, however, have recently been proved by Brefeld to be a 

 conidial form of reproduction of the Nyctalis.
