Fulvifomes nonggangensis and F. tubogeneratus (Hymenochaetales, Basidiomycota): Two New Species from Southern China Based on Morphological and Molecular Evidences

Two new species of Fulvifomes are described from specimens collected in rainforests of Nonggang Nature Reserve of southern China, based on morphological characteristics and molecular phylogenetic analysis of the internal transcribed spacer (ITS) and nuclear large subunit ribosomal DNA (nLSU) sequences. Fulvifomes nonggangensis sp. nov. is characterized by perennial, sessile and solitary basidiocarps, applanate pileus, small cystidioles of 9.9–15.4 Â 2.9–3.5 lm, large pores of 5–6 per mm, a dimitic hyphal system, and broadly ellipsoid basidiospores of 4.3–5.3 Â 3.3–4.2 lm. F. tubogeneratus sp. nov. is characterized by perennial, sessile, and imbricate basidiocarps, a duplex context, small pores of 7–8 per mm, a dimitic hyphal system, and ovoid to subglobose basidiospores of 5.72 Â 5.00 lm.

Amylosporus sulcatus sp. nov. (Russulales, Basidiomycota) from Southern China

Amylosporus sulcatus sp. nov. is described from Nonggang Nature Reserve, southern China, on the basis of morphological and molecular data. The morphological description and illustrations for the new species are provided. The species is characterized by pileate and stipitate basidiocarps. The pileus surface is obviously concentrically and radiately sulcate and tomentum, and the pore surface is snow white. Phylogenetic analyses based on sequences of the internal transcribed spacer and nuclear large subunit ribosomal DNA confirmed it to be a new species.
