Fibroporia Angulopora, A New Species (Aphyllophorales, Polyporaceae) Associated with Brown-Rot of Pseudotsuga Menziesii Residue in Western Oregon

ABSTRACT

A new wood-inhabiting basidiomycete, Fibroporia angulopora, is described from the Cascade Mountains in western Oregon. The fungus is associated with a brown-rot decay of Douglas-fir residue in old growth stands. Characteristics derived from studies of fruiting bodies and cultures are presented and incompatibility system (mating type) determined. The generic position of F. angulopora is discussed with reference to Fibuloporia and Strangulidium.
