Notes on New Zealand polypores (Basidiomycetes) 2. Cultural and morphological studies of selected species

Abstract The taxonomic positions of several New Zealand polypore fungi were examined using morphological, cultural, sexual, and nuclear criteria. Postia venata (Rajchenb. & Wright) Rajchenb., previously described from Nothofagus forests in Argentina, is newly recorded in New Zealand on Nothofagus spp. It is distinct from Postia atrostrigosa (Cooke) comb. nov., which has a pileated fruit body and wider, strictly allantoid, IKI+ basidio‐spores. Postia venata is also distinct from Tyromyces setiger (Cooke) G.H. Cunn., which has a pileated, uniformly strigose, white, triquetrous fruit body, and strictly allantoid spores. Skeletocutis stramenticus (G.H. Cunn.) comb. nov. is shown to be conspecific with S. australis Rajchenb., also reported from Argentina. Polyporus hemitephrus Berk, is a white rotting wood decay species and belongs in Fomes (Fr.) Fr. Cultural descriptions are given for Fomes hemitephrus (Berk.) Cooke, P. venata , and Schizopora nothofagi (G.H. Cunn.) P.K. Buchanan & Ryv. Cultural evidence supports the close relationship between Schizopora Vél. and Hyphodontia J. Erikss. Morphological features of the fruit bodies and cultural data support the synonymity of Poria coprosmae G.H. Cunn. with Skeletocutis nivea (Jungh.) Keller.
