Morphological description
Fruiting body. Basidiomata annual, effused to effusedreflexed, subceraceous to subgelatinous, without odour or taste when fresh, becoming crustaceous upon drying. Pilei flabelliform, projecting up to 2 cm wide, 1.5 mm thick at centre. Pileal surface tomentose, white to cream when fresh and grey upon drying. Hymenophore merulioid, straw-yellow when fresh, turning to buff and orange-yellow or fawn upon drying. Sterile margin distinct, white, fimbriate.
Hyphal structure. Monomitic; hyphae clamped, colourless, thin-walled, sparsely branched, IKI–, CB–; tissues unchanged in KOH. Contextual hyphae subparallel, 2.5–4 μm in diam.; subhymenial hyphae infrequently branched, 2–3.5 μm in diam.
Hymenium. Cystidia absent; fusoid cystidioles present, colourless, thin-walled, 13–20 × 1.5–2.5 μm; basidia clavate, with four sterigmata and a basal clamp connection, 14–20 × 2.5–4.5 μm. Basidiospores allantoid, colourless, thin-walled, smooth, often with 2–3 oildrops, IKI–, CB–, 3.5–4.5 × 1– 1.4 μm, L = 4.01 μm, W = 1.18 μm, Q = 3.01–3.51 (n = 360/ 12); in holotype 3.5–4.2 × 1–1.3 μm, L = 3.93 μm, W =1.16 μm, Q = 3.39 (n = 30/1).

Distribution: In southern China.
