Fungal Names: FN 571652.
Etymology: tianzhongshanensis (Latin), referring to the species being found in Tianzhongshan.
Diagnosis: Differing from Physalacria auricularioides by smaller basidia and basidiospores, sessile, whitish to cream, soft coriaceous basidiomes.
Description: Basidiomes soft coriaceous, more or less gelatinous when fresh, whitish to cream, single, scattered, in group, 2–5 mm, discoid-peltate, cupulate, sessile, hymenial surface smooth, negative geotropic, becoming coriaceous and cream to buff after drying. Margin not lobed and rounded. Hyphal system monomitic; usually simple septate, hyaline, thin-walled, and 0.5–2.0 µm in diam. Basidia clavate or cylindrical, thin-walled, with 1–4 sterigmata up to 4 μm long, 17.2–37.2 × 6.2–7.8 μm; basidioles similar in shape to basidia, but smaller. Basidiospores hyaline, thin-walled, smooth, subglobose, ellipsoid to ovoid, subovoid, subcitriform, lacrymoid, usually with one or two oil drops, (5.8–)6.5–10.2(−11.0) × (4.0–)4.5–5.5(−5.8) µm, L = 8.12 µm, W = 5.07 µm, Q = 1.59 (n = 30/1). Cystidia subfusiform, apex narrow, thin-walled, colourless and hyaline, 34.5–42.2 × 9.5–11.4 μm.
Materials examined: China. Zhejiang Province, Hangzhou City, Fuyang District, Tianzhongshan, on fallen angiosperm branch, 26 March 2023, Wu 653 (holotype in BJFC039977), Wu 907 (BJFC040387).
