Morphological description
Fruiting body. Basidiomata annual, effused, easily detachable, subceraceous to subgelatinous, without odour or taste when fresh, becoming coriaceous upon drying, up to 25 cm long, 600–900 μm thick. Hymenial surface tuberculate, greyish brown to brown when fresh, brown upon drying. Sterile margin narrow, brown.
Hyphal structure. Monomitic; generative hyphae clamped at all primary septa, colourless, thin-walled, IKI–, CB–; tissues unchanged in KOH. Subicular hyphae infrequently branched, 2.5–4.5 μm in diam.; subhymenial hyphae infrequently branched, 2–4 μm in diam.
Hymenium. Cystidia fusiform, numerous, thin-walled, apically encrusted with large crystals, 23.5–37 × 5.5–6.5 μm; cylindrical cystidioles present, colourless, thin-walled, 11– 15.5 × 1.5–4.5 μm; basidia clavate, with four sterigmata and a basal clamp connection, 20–28 × 3.5–5.5 μm. Basidiospores ellipsoid, colourless, thin-walled, smooth, often with 1–2 oildrops, IKI–, CB–, 3.5–4.5 × 2–3.2 μm, L = 3.98 μm, W = 2.76μm, Q = 1.41–1.47 (n = 60/2); inholotype 3.8–4.5 × 2.3–3.2 μm, L = 4.2 μm, W = 2.86 μm, Q = 1.47 (n = 30/1).

Distribution: In Yunnan Province of China.
