Wang & C.L. Zhao , sp. nov. Figs. 4 and 5 . MycoBank no.: 851548. Etymology : — sinensis (Lat.) : refers to the locality ( China ) of the type specimen. Holotype : — CHINA . Yunnan Province , Qujing , Qilin District , Cuishan Forest Park , GPS coordinates: 25°55′ N, 103°69′ E, altitude: 2245 m asl., on the fallen branch of angiosperm, leg. C.L. Zhao , 27 October 2022 , CLZhao 25866 ( SWFC ) . Basidiomata : —Annual, resupinate, adnate, membranaceous, and up to 10 cm long, 4 cm wide and 0.1 mm thick. Hymenial surface smooth, white to slightly greyish when fresh, become greyish to honey yellow when dry. Sterile margin indistinct, white to slightly greyish, up to 1 mm . Hyphal system : —Monomitic; generative hyphae with clamp connections, colorless, thin-walled, frequently branched, interwoven, 3–4.5 µm in diameter; IKI–, CB–, tissues unchanged in KOH. Hymenium : —Cystidia clavate, colorless, thin-walled, 18–30 × 2–3 µm. Basidia clavate, colorless, thin-walled, with a basal clamp connection and four sterigmata, 14.5–16 × 3–4 µm; basidioles dominant, in shape similar to basidia, but slightly smaller. Spores : —Basidiospores broadly ellipsoid, colorless, thin-walled, smooth, IKI–, CB–, 4–6(–6.5) × (2.5–)3–4 µm, L = 5.24 µm, W = 3.63 µm, Q = 1.32–1.44 (n = 90/3). FIGURE 2 . Candelabrochaete yunnanensis (holotype, CLZhao 26027): basidiomata on the substrate (A), macroscopic characteristics of hymenophore (B). Bars: (A) = 1 cm and (B) = 1 mm. FIGURE 3 . Microscopic structures of Candelabrochaete yunnanensis (holotype, CLZhao 26027): basidiospores (A), basidia and basidioles (B), cystidia (C), a section of the hymenium (D). Bars: A= 5 µm, (B–D) = 10 µm. Additional specimens examined : — CHINA .
