PvROPOLYPORUS ALBOMARGINATUS (Lev.) Murrill, Bull. Torrey 

 Club 34: 478. 1907. PolyporusochrocroceusY.Yi&\\x\. (Mon- 

 sunia i : 145. 1899.) exactly corresponds to this species, 

 judging from the description, and should be treated as a .syn- 

 onym. 



Luzon : Bosoboso, Rizal Province, Ramos, {214^), {2150), 

 {2ij6) ; Lamao River, Bataan Province, Copeland lyj ; Mt. Mar- 

 iveles, Bataan Province, Merrill, (jdpS). Mindanao : Mt. Apo, 

 Davao, Copeland loyj. A specimen collected at Camp Keithley 

 by Airs. Clemens agrees well with Fomes pyrrhocreas Cooke, which 

 I have considered synonymous with P. albomarginatus. It may be 

 that further collections will prove them distinct species.
