Two New Species of (Hymenochaetales, Basidiomycota) from Southwest China.

Two new wood-inhabiting fungi, sp. Nov. and sp. Nov. in the order Hymenochaetales from southwest China, are described and illustrated based on molecular and morphological evidence. They were found on gymnosperm wood that is rotten and charred. The characteristics of include annual, resupinate basidioma, salmon pores with distinctly white margins, angular pores (7-9 per mm), a dimitic hyphal system, and lunate basidiospores that are 3-3.5 × 0.9-1.1 μm. The characteristics of include annual, resupinate basidioma with a white to cream fresh pore surface that becomes cream to honey-yellow and shiny when dry, round pores (7-8 per mm), a dimitic hyphal system, and lunate basidiospores that measure 2.9-3.1 × 1-1.1 μm. A phylogenetic analysis based on the combined 2-locus dataset (5.8S + nuclear large subunit RNA (nLSU)) shows that the two species are members of the genus , and they are morphologically compared with related species, respectively. This paper provides a key to the identification of 16 accepted species of that are found throughout the world.
