Holotype: China. Yunnan Province, Pu’er, Jingdong County, Wuliangshan National Nature Reserve , on fallen angiosperm branch, 6 October 2017, CLZhao 4479 ( SWFC).
Etymology: xanthum (Lat.) : referring to the buff hymenial surface of the type specimen.
Basidiomata: Annual, resupinate, adnate, without odour or taste when fresh, becoming membranaceous up on drying, up to 10 cm long, 4 cm wide, 100–200 μm thick. Hymenial surface odontioid, with round aculei, 5–6 per mm, 0.1–0.3 mm long, white to cream when fresh, turning buff to yellow upon drying.
Hyphal structure: Hyphal system monomitic, generative hyphae with clamp connections, colourless, thin-walled, branched, covered by crystals, interwoven, 2–4.5 μm in diameter; IKI–, CB –; tissues unchanged in KOH.
Hymenium: Cystidia numerous, strongly encrusted in the apical part, 35.5–125 × 5–9 μm; cystidioles absent. Basidia clavate, with 4-sterigmata and basal clamp connections, 10–
19.3 × 3–5.2 μm, basidioles dominant, in a shape similar to basidia, but slightly smaller.
Spores: Basidiospores ellipsoid, colourless, smooth, thin-walled, with oil drops, IKI–, CB –, 2.7–5(–5.6) × 2–3.9(–4.4) μm, L = 3.48 μm, W = 2.63 μm, Q = 1.25–1.41 (n = 240/9).
Additional specimens (paratypes) examined: China. Yunnan Province, Pu’er, Zhenyuan County, Heping town , Jinshan Forest Park, on fallen angiosperm trunk, 12 January 2018, CLZhao 5024, 5032, 5044 ( SWFC) ; 21 August 2018, CLZhao 8124 ( SWFC) ; on fallen angiosperm branch 12 January 2018, CLZhao 5030 ( SWFC) ; Jingdong County, Wuliangshan National Nature Reserve , on fallen angiosperm trunk, 6 October 2017, CLZhao 4381 ( SWFC) .
