Efibula glossophora Z. R Gu & C. L. Zhao 2025, sp. nov.

Efibula glossophora Z. R Gu & C. L. Zhao sp. nov. Figs 8, 9, 10 Diagnosis. Differs from other Efibula species by its hard, membranous, slightly yellow to yellow basidiomata; a monomitic hyphal system with simple-septa generative hyphae; and ellipsoid basidiospores measuring 3.8–6 × 2.6–3.7 µm. Holotype. China • Yunnan Province, Dali, Weishan County, Leqiu Town, Zhongyao Village, GPS coordinates: 25°01'N, 100°4'E, altitude 1900 m asl., on the fallen angiosperm branch, leg. C. L. Zhao, 19 July 2022, CLZhao 22744, GenBank: ITS = PV 470540, nLSU = PV 474185 (SWFC). Etymology. Glossophora (Latin or Greek origin): refers to the smooth hymenial surface of the type specimen. Description. Basidiomata. Annual, resupinate, closely adnate, hard membranaceous, without odor or taste when fresh, up to 9 cm long, 2.5 cm wide, and 300 μm thick at center. Hymenophore smooth, buff to slightly yellow when fresh, slightly yellow to yellow upon drying. Sterile margin narrow, cream to slightly yellow, up to 1 mm. Hyphal system. Monomitic; generative hyphae with simple septa, colorless, thin- to slightly thick-walled, smooth, rarely branched, interwoven, 3–3.5 µm in diameter, IKI –, CB –; tissues unchanged in KOH. Hymenium. Cystidia and cystidioles absent. Basidia long clavate, slightly flexuous, with four sterigmata and a simple septum at the base, 21.5–26.7 × 5.7–7.4 µm; basidioles numerous, in shape similar to basidia but smaller. Basidiospores. Basidiospores ellipsoid, colorless, thin-walled, smooth, IKI –, CB –, (3.6 –) 3.8–6 (– 7.5) × (2 –) 2.6–3.7 (– 4.3) µm, L = 5.3 µm, W = 3.3 µm, Q = 1.63 (n = 30 / 1).
