China, • Yunnan Province, Puer, Jinggu County, Weiyuanjiang Provincial Nature Reserve, 23°11'N, 100°33'E, elevation 1,005 m asl., on fallen angiosperm branch, leg. C. L. Zhao, 3 October 2025, CLZhao 47454 (SWFC 00047454). Etymology. Albomarginata (Lat.) refers to the white margin of the type specimens. Basidiomata. Annual, resupinate, closely adnate, membranaceous, without odor or taste when fresh, becoming fragile upon drying, up to 4 cm long, 2 cm wide, 150 µm thick. Hymenial surface smooth, cream when fresh, cream to buff upon drying. Sterile margin white, narrow, up to 1 mm wide. Hyphal structure. Monomitic, generative hyphae with simple septate, colorless, thin-walled, branched, interwoven, 2.5–6.5 µm in diameter, IKI –, CB –; tissues unchanged in KOH. Hymenium. Cystidia abundant, embedded or slightly projecting, tapering, distinctly thin-walled, occasionally with oil drops, without crystals, 27–59 × 5–6.5 µm. Basidia clavate, occasionally with oil drops, with four sterigmata and a basal simple septum, 25–32 × 6–7.5 µm; basidioles dominant, occasionally with oil drops, similar to basidia in shape, but slightly smaller. Basidiospores. Ellipsoid, colorless, smooth, thin-walled, often with oily drops, IKI –, CB –, (6.8 –) 7.1–9.2 (– 9.4) × (4 –) 4.1–4.9 (– 5.3) µm, L = 8.07 µm, W = 4.60 µm, Qm = 1.76 ± 0.14 (n = 30 / 1). Type of rot. White rot.
