Etymology:— yunnanensis (Lat.) refers to the location “ Yunnan Province ” where the type specimen was collected.
Holotype:— CHINA. Yunnan Province, Lijiang, Yulong County, Black Dragon Pool Park , E 100°13′57′′, N 26°53′15′′, elev. 2417 m, on the stump of angiosperm, 21 July 2021, CLZhao 21647 ( SWFC). GoogleMaps
Fruiting body:— Basidiomata annual, resupinate, soft to juicy when fresh, without odor or taste, bone hard when dry, up to 3 cm long, 2.5 cm wide and 0.5 mm thick at centre. Pore surface olivaceous when fresh, olivaceous to black when dry, slightly staining when touched or bruised; sterile margin narrow, up to 1 mm wide; pores round, shallow, 2–3 per mm; dissepiments thin, entire. Subiculum very thin to almost lacking, olivaceous to brown, hard corky. Tubes concolourous with the pore surface, bone hard, up to 0.4 mm long.
Hyphal structure: — Hyphal system monomitic; generative hyphae with simple septa, IKI-, CB+; tissues unchanged in KOH.
Subiculum: — Subicular generative hyphae colorless, thin to slightly thick-walled, occasionally branched, more or less straight, regularly arranged, 4–6 µm in diam.
Hymenium : — Tramal generative hyphae colorless, thin to slightly thick-walled, moderately branched, interwoven, 3.5–5.5 µm in diam; cystidia larger, strongly encrusted, colorless, thin-walled, 30–76 × 5–8.5 µm; basidia mostly short clavate to barrel-shaped, thin-walled, smooth, with four sterigmata and a simple basal septum, 8–11.5 × 5.5–7 µm (x̅ = 9.8 × 6.3 µm); basidioles in shape similar to basidia, but smaller.
Basidiospores: — Subglobose, colorless, thin-walled, smooth, bearing a larger guttule, IKI-, CB-, 4–5.5 × 3.5–5 µm, L = 4.5 µm, W = 4 µm, Q = 1.04–1.08 (n = 60/2).
Additional specimens examined: — CHINA. Yunnan Province, Lijiang, Yulong County, Black Dragon Pool Park , E 100°13′57′′, N 26°53′15′′, elev. 2417 m, on the stump of angiosperm, 21 July 2021, CLZhao 21583 ( SWFC) GoogleMaps .
