Holotype.

China • Yunnan Province, Lincang, Fengqing County, Yaojie Town, Xingyuan Village , GPS coordinates 24°58'N, 99°92'E, altitude 1600 m asl., on the fallen branch of angiosperm, leg. C. L. Zhao, 22 October 2022, CLZhao 25667 ( SWFC).

Etymology.

sinensis (Lat.): referring to the locality ( China) of the type specimen.

Basidiomata.

Annual, resupinate, adnate, soft coriaceous, without odour or taste, becoming hard coriaceous upon drying, up to 20 cm long, 2 cm wide, 100–150 µm thick. Hymenial surface tuberculate, buff to slightly straw when fresh, turning to straw to cinnamon to ocherous upon drying. Sterile margin cream to slightly straw, abrupt, up to 1 mm wide.

Hyphal system.

Monomitic, generative hyphae with clamp connections, colorless, thin-walled, branched, interwoven, 2.5–3.5 µm in diameter; IKI –, CB –, tissues unchanged in KOH.

Hymenium.

Cystidia and cystidioles absent. Basidia clavate, with 4 sterigmata and a basal clamp connection, with a median constriction, 35–41.5 × 7.5–9.5 µm; basidioles dominant, similar to basidia in shape, but slightly smaller.

Basidiospores.

Broadly ellipsoid, slightly thick-walled, smooth, colorless, some with guttulae, CB +, 7.5–9 (– 9.5) × (5.8 –) 6.2–7.5 (– 7.7) µm, L = 8.42 µm, W = 6.88 µm, Q = 1.10–1.33, Q m = 1.23 ± 0.08 (n = 30 / 1).
