Holotype.

China • Yunnan Province, Wenshan Zhuang and Miao Autonomous Region, Xichou County, Xiaoqiaogou Forest Farm , on fallen angiosperm trunk, 29 June 2019, Dai 19957 ( BJFC 031631 About BJFC ).

Etymology.

Subtropica (Lat.): refers to the species being found in subtropical area.

Description.

Basidiomata. Annual, resupinate, inseparable from the substrate, without odor or taste and corky when fresh, rigid when dry, up to 15 cm long, 8 cm wide and 2.5 mm thick at center. Pore surface grayish brown to honey-yellow; sterile margin indistinct, curry-yellow, up to 1 mm wide; pores irregular to angular, sometimes sinuous, 3–5 per mm; dissepiments thin, entire, abundant setae seen in tube cavities (under lens). Subiculum clay-buff, corky, about 0.5 mm thick. Tubes olivaceous buff, up to 2 mm long.

Hyphal structure. Hyphal system dimitic; generative hyphae simple septate; tissue becoming black in KOH.

Subiculum. Generative hyphae infrequently, thin-walled, frequently branched, simple septate, 2–3 μm in diam; skeletal hyphae dominant, yellowish brown, thick-walled with a medium lumen, unbranched, aseptate, flexuous, strongly interwoven, 3–4 μm in diam.

Tubes. Generative hyphae infrequent, mostly present at subhymenium, hyaline, thin-walled, frequently branched, simple septate, 2–3 μm in diam; skeletal hyphae dominant, yellowish brown, thick-walled with a narrow to medium lumen, unbranched, aseptate, loosely interwoven, 2–4 μm in diam. Setae frequent, mostly originating from hymenium, subulate, dark brown, thick-walled, 35–55 × 4–7 μm; fusoid cystidioles frequent, hyaline and thin-walled, 18–26 × 4–6 μm; basidia barrel-shaped, with four sterigmata and a simple septum at the base, 14–18 × 4–6 μm; basidioles in shape similar to basidia, but slightly smaller.

Basidiospores. Basidiospores cylindric, hyaline, thin-walled, smooth, IKI –, CB –, (5.5 –) 6–7.5 (– 8) × 2–3 (– 3.2) μm, L = 6.91 μm, W = 2.66 μm, Q = 2.32–2.71 (n = 50 / 2).
