this fact combined with the lack of any specific type is sure to 
involve any forms referred to Secretan’s species in confusion 
with the Friesian species; third, the Friesian species itself, as we 
believe, is of doubtful standing and further confusion is likely to 
be involved with its synonyms ; finally, the American form does 
not appear to be represented in Europe and there is, therefore, 
reason for serious doubt if Secretan really described the Ameri- 
can species.

No specimen whatever referred to Hydnumz'elntinum Fries was 
found at Upsala. There is probably, therefore, no type specimen 
of this species. At Berlin no specimens were found under this 
name except a couple of American plants sent by Atkinson. At 
Paris, besides a specimen from Massachusetts collected by Sprague, 
there was only one other specimen which had been collected in 
“ Nantes.” At Kew, England, a considerable number of speci- 
mens were found under this name, many of which were iden- 
tical with the American H. spongiosipcs Pk. as were also the 
specimens at Berlin and Paris. The latter species is, therefore, 
evidently a European species though apparently rare on the con- 
tinent and is known to the European mycologists as Hydnum 
velutinum Eries with the description of which it fully accords.
