Phylogeny and taxonomy of Nigroporus (Polyporales, Basidiomycota) with four new species from Asia and Oceania.

ABSTRACT: Nigroporusvinosus (Berk.) Murrill, first described from North America, was considered to be a common species in China. The existence of a species complex is confirmed through a phylogenetic analysis of samples examined. Based on morphological examination and molecular evidence, four new species are described as Nigroporusaustralianus, N.austroasianus, N.subvinosus and N.yunnanensis. They are characterized by pileate, effused-reflexed to resupinate, purplish, vinaceous to brown basidiomata when fresh, mostly becoming brown when dry. Nigroporusaustralianus is characterized by narrower basidiospores measuring 3.4-4.1 × 1.3-1.5 µm, thicker contextual hyphae measuring 3.2-6.4 µm in diam and a geographical distribution in Australia.
