Banker: Type Studies in the Hydnaceae 275 



Echinus Scop, is evidently known only from Scopoli's original 

 description, ''Anni historico-naturales " 4: 151. 1770.^ The 

 work is little known and we have not seen a copy. So far as 

 later descriptions give one a conception of the plant, it appears 

 that it might be some form of a branching C lav aria. Hydnum 

 Notarisii Inz. and H. alpestre Pers. are the only species of the 

 genus of which authentic specimens are in existence. The speci- 

 men of H. Notarisii Inz. on which Fries based his description 

 and comments is now preserved in the herbarium at Upsala. It 

 has every appearance of being a form of Hydnum Erinaceus 

 Bull, with an unusually long stipe. There appears to be nothing 

 whatever about the specimen to suggest but that it grew with 

 the teeth pendent. The statement " Ob clavam oblique deflexam 

 aculei horizontaliter porrecti " appears to be based on accidental 

 inversion of the plant. Inzenga's type has not been seen unless 

 the Friesian specimen is a part of it. In the herbarium of Per- 

 soon at Leyden was found a small piece of a specimen marked 

 Hericium alpestre (Helvetia)." This had every appearance of 

 being a fragment of H. coralloides Scop, and we do not believe 

 the Persoonian species is distinct from the latter, at least, it is 

 certainly of the same genus. 



From our present knowledge of these forms the most that can 

 be said is that Martella Scop. (=Hericium Fr. " Hym. Eur." 

 617) is a genus of very doubtful standing. The genus Manina 

 Scop., however, is a well-defined genus that has long been recog- 

 nized by mycologists under various names.
