232 Murrill: Polyporaceae of North America 



Georgia (Ellis), Ohio (James, Morgan), Delaware (Commons), 

 New York (Earle, Underwood), Massachusetts (Underwood), 

 Pennsylvania (Herbst), Florida (Martin), New Jersey (Ellis), Mis- 

 souri (Glatfelter). 



The favorite host of this species is the maple, though it is also 

 found on poplar, linden and a few other deciduous trees. Living 

 Norway maples in Sweden were found to be seriously injured by 

 its attacks, and I have noticed it on this and other species of 

 maple used as shade-trees in American cities. 



12. Fomes Meliae (Underw.) 



Polyporits Meliae Underw. Bull. Torrey Club, 24: 85. 1897. 



Described from specimens collected by Underwood on branches 



of Melia Asederach in 1895. It also occurs on Gleditsia and 



Fraxiniis, as is indicated by the recent Alabama collections of 



Earle and Baker.

 Fomes geotropus Cooke, Grevillea, 13: 119. 1^2,4. {Polyponis 

 geotroptcs Cooke, GrQvxWe^i, 1^: 32. 1884). This species is allied 

 to Fomes ulmarius Fr. It was described from collections in Dem- 

 erara, but seems to range northward to Mexico, Florida and Ala- 

 bama. Other doubtful or unknown species are : Fomes pcrpusilliis 

 (Pers.) Cooke, F. extensiis (Lev.) Cooke, F. aegerita (Fr.) Cooke, 



F. microporus (Sw.) Cooke, and F. albogriseus Peck,
