New Species of Fungi from various Localities with Notes on some 



published Species 



By J. B. Ellis and B. M. Everhart 



Echinodontium E. & E. nov. gen. (Family Hydnaceae). 



Differs from Hydnum in the thick, woody pileus of Fames and 

 the teeth beset with spines, as in Mncronoporus and Hymenochaete.

In the specimen from which Fames tinctorius was described the 

 teeth were all broken off so as to resemble a Polyporus : but what 

 were taken for pores were only the hollow bases of the brittle, 

 cinereous teeth which, in the Idaho specimens are about 1 cm. long 

 and 1.5-2 mm thick at the base. The hymenial surface is rather 

 sparingly clothed with subconical, reddish -brown spines, 20-30 X 

 "~7 !>■■ The spores at first are nearly hyaline. 



The characters of this fungus differ so much from Hydnum that 

 we propose it here as a new genus.
