Candelabrochaete yunnanensis L. Wang & C.L. Zhao , sp. nov. Figs. 2 and 3 .

MycoBank no.: 851547

Etymology: — yunnanensis (Lat.) : refers to the locality (Yunnan Province) 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, 24 November 2022, CLZhao 26027 ( SWFC) .

Basidiomata: —Annual, resupinate, closely adnate, farinaceous, up to 12 cm long, 5 cm wide and 0.3 mm thick. Hymenial surface smooth, flesh-pinkish to brownish vinaceous when fresh, become pinkish buff to buff when dry. Sterile margin thinning, adnate, pinkish buff to buff, up to 1 mm.

Hyphal system: —Monomitic; generative hyphae simple-septate, colorless, distinctly thick-walled, usually branched at a right angle, interwoven, 3.5–6 µm in diameter; IKI–, CB–, tissues unchanged in KOH.

Hymenium: —Septocystidia abundant, cylindrical, slightly sinuous, frequently septate, colorless, thick-walled, arising from the subiculum, mostly embedded, 80–105 × 7–9 µm. Basidia barreled, colorless, thin-walled, encrusted with crystals, with a basal simple septum and four sterigmata, 16–18 × 4.5–5.5 µm; basidioles dominant, in shape similar to basidia, but slightly smaller.

Spores: —Basidiospores ellipsoid, colorless, thin-walled, smooth, IKI–, CB–, 4–5 × 2.5–3(–4) µm, L = 4.84 µm, W = 3.18 µm, Q = 1.53 (n = 30/1).
