A new species of Fulvifomes (Hymenochaetaceae) from Cambodia
Fulvifomes cambodiensis sp. nov. is described and illustrated from Preah Vihear, Cambodia. It produces perennial, pileate and solitary basidiomes with a concentrically sulcate zonate pileal surface, homogeneous context, hymenial setae, and yellowish acyanophilous basidiospores.
The new species macroscopically resembles F. rimosus, which differs in lacking hymenial setae and having cyanophilous generative hyphae and slightly smaller basidiospores. The macroscopically similar Fomitiporia hartigii is distinguished by larger hyaline basidiospores and the
absence of setae. Fulvifomes johnsonianus has abundant hymenial setae and quite similar hyphal structure to F. cambodiensis, but its much smaller basidiospores and effused-reflexed to pileate basidiomes distinguish it from the new species with pileate and ungulate basidiomes
with cracked pileal surface.
