MycoBank: 838579

Type:China. Hainan Province, Lingshui County, Diaoluoshan Forest Park, 18°42'N, 109°49'E, rotten angiosperm wood, 13.XI.2015, Y.C. Dai 16107 (holotype BJFC020200).

Description:

Sexual morph: Basidiomata. Annual, effused-reflexed, soft corky, without odor or taste when fresh, becoming corky upon drying, resupinating up to 5.5 cm long, 3 cm wide and 1.3 mm thick, with a pileal projection up to 0.6 cm, 2.3 cm wide and 1.3 mm thick at base. Pileal surface pinkish buff to clay-buff, glabrous and faintly zonate when dry; margin acute. Pore surface clay-buff to pale brown, bruised part becoming dark brown to black when dry, shiny; sterile margin up to 2 mm wide; pores round or sometimes angular, 6–8 per mm; dissepiments thin, entire. Context pale cream, slightly fibrous to corky, up to 0.5 mm thick. Tubes concolorous with the pore surface, darker than context, corky, up to 0.8 mm long, with a distinct dark line between tubes and context. Tubes. Hyphae thin- to slightly thick-walled, frequently branched, agglutinated and loosely interwoven, 2.5–3.5 μm in diam. Cystidia and cystidioles absent. Basidia clavate to more or less pyriform, with four sterigmata and a basal clamp connection, 10–12 × 4–5.5 μm; basidioles of similar shape to basidia, but smaller. Crystals present among hymenium. Basidiospores. Ellipsoid to broadly ellipsoid, hyaline, thin-walled, smooth, CB–, IKI–, (3.8–)3.9–4.5 × (2.6–)2.8–3.3(–3.4) μm, L = 4.21 μm, W = 3.02 μm, Q = 1.37–1.43 (n = 90/3).
