Zhao sp. nov.</p><p>Figs 11, 12, 13</p><p><b>Diagnosis.</b></p><p>Differs from other <i>Efibula</i> species by its membranaceous, slightly gray to pale brown basidiomata, a monomitic hyphal system with simple-septate generative hyphae, and ellipsoid basidiospores measuring 4.3–6.2 × 2.2–3.3 µm.</p><p><b>Holotype.</b></p><p>China • Yunnan Province, Dehong, Yingjiang County, Tongbiguan Provincial Nature Reserve, GPS coordinates: 27°77'N, 104°25'E, altitude 1900 m asl., on the fallen angiosperm branch, leg. C. L. Zhao, 18 July 2023, CLZhao 30011, GenBank: ITS = PV 470544, nLSU = PV 474189 (SWFC).</p><p><b>Etymology.</b></p><p><i>Punctata</i> (Latin or Greek origin): refers to the species having cushion-shaped hymenial surface of the type specimens.</p><p><b>Description.</b></p><p><b><i>Basidiomata</i>.</b> Annual, resupinate, closely adnate, thin membranaceous, without odor or taste when fresh, up to 10 cm long, 2 cm wide, and 200 μm thick at center. Hymenophore smooth, cream to slightly brown when fresh, slightly gray to pale brown upon drying. Sterile margin narrow, cream to slightly brown, up to 1 mm.</p><p><b><i>Hyphal system</i>.</b> Monomitic; generative hyphae with simple septa, colorless, thin-walled, smooth, branched, interwoven, 1.5–3.5 µm in diameter; IKI –, CB –; tissues unchanged in KOH. <b><i>Hymenium</i>.</b> Cystidia absent, cystidoles mostly subfusiform, colorless, thin-walled, smooth, 9.8–22 × 2.8–5.7 µm. Basidia subcylindrical to subclavate, slightly flexuous, with a basal simple septum and four sterigmata, 11.8–19.4 × 3.7–5.9 µm; basidioles numerous, in shape similar to basidia but smaller. <b><i>Basidiospores</i>.</b> Basidiospores ellipsoid, colorless, thin-walled, IKI –, CB –, (3.6 –) 4.3–6.2 (– 6.7) × (1.8 –) 2.2–3.3 (– 3.9) µm, L = 5.17 µm, W = 2.74 µm, Q = 1.81–1.92 (n = 240 / 8).</p><p><b>Additional specimens examined (paratypes).</b></p><p>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.
