Abstract

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

Keywords: Polypore, phylogeny, taxonomy, wood-inhabiting fungi, China

Diagnosis.— Differs from other Ceriporia species by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 μm. 

Type.— CHINA. Hainan Prov.: Qiongzhong County, Limushan Nat. Res., on rotten angiosperm wood, 30 May 2015, Dai 15205 (holotype in BJFC!).

Etymology.— Albomellea (Lat.) refers to the white to cinnamon-buff pore surface.
