Pyropolyporus praerimosus Murrill 



Not specifically distinct from Fulvifomes Everhartii (Ellis & 

 Gall.) Murrill. 



Pyropolyporus juniperinus (Schrenk) Murrill 



Fomes Demidoffii is said to be the same thing. If so, this name 

 will have to be taken up, since it is much older. According to 

 Saccardo, Fomes Demidoffii Lev. occurs "ad truncos Juniperi 

 excelsae in Europa et Pini silvestris pr. Minussink Sibiriae Asia- 

 ticae." The description agrees fairly well with that of P. juni- 

 perinus. 



Pyropolyorus Earlei Murrill 



Not specifically distinct from Fulvifomes juniperinus ( Schrenk) 

 Murrill. 



Globifomes graveolens (Schw.) Murrill 

 Polyp or us botryoides Lev. is probably not distinct. 



Elfvingia P. Karst. 



Species having hyaline or subhyaline spores were transferred 

 to the new genus, Elfvingiella Murrill, in " Northern Polypores," 

 " Southern Polypores," " Western Polypores," and " Tropical 

 Polypores." 



Elfvingia fasciata (Sw.) Murrill 



The validity of the specific name is in doubt and it may be 

 advisable to use the combination Elfvingiella marmorata (Berk. 

 & Curt.) Murrill for this species. 



Elfvingia megaloma (Lev.) Murrill 



Many authors prefer Fomes applanatus for this species, claim- 

 ing that there is no specific difference between the American and 

 European plants. The earliest name for Fomes applanatus is 

 Boletus lipsiensis Batsch, 1786, and this was taken up in 1903 as 

 Elfvingia lipsiensis (Batsch) Murrill. ' •
