Zhao sp. nov. Figs 8 , 9 Type material. Holotype . China. Yunnan Province, Honghe, Pingbian County, Daweishan National Nature Reserve, 22°53'26"N , 103°35'37"E , altitude 1990 m a.s.l., on angiosperm trunk, leg. C.L. Zhao, 3 August 2019, CLZhao 18357 (SWFC). Etymology. Daweishanensis (Lat.): referring to the locality (Daweishan) of the type specimen. Description. Basidiomata annual, resupinate, adnate, without odor or taste when fresh, coriaceous, up to 10 cm long, 5 cm wide, and 150 µm thick. Hymenial surface odontioid, slightly buff when fresh, and buff upon drying. Margin sterile, slightly buff, and 1 mm wide. Hyphal system monomitic, generative hyphae with clamp connections, colorless, thin to thick-walled, frequently branched, interwoven, 1.5-4 µm in diameter, IKI-, CB-, tissues unchanged in KOH. Figure 8. Basidiomata of Xylodon daweishanensis (holotype). Scale bars: 2 cm ( A ); 1 mm ( B ). Cystidia of two types: (1) capitate cystidia thin-walled, smooth, slightly constricted at the neck, with a globose tip, 11-23.5 x 2.5-5 µm ; (2) asterocystidia thin-walled, with the apical part encrusted, 11-26.5 x 2.5-4.5 µm ; basidia clavate to subcylindrical, constricted, somewhat sinuous, with four sterigmata and a basal clamp connection, 11-15.5 x 2.5-4 µm .

Scale bars: 5 µm ( A ); 10 µm ( B-E ). Basidiospores broad ellipsoid to subglobose, colorless, thin-walled, smooth, with oil drops, IKI-, CB-, 3-4 x 2.5-3.5(-4) µm , L = 3.51 µm , W = 3.14 µm , Q = 1.09-1.15 (n = 150/5).
