Zhao , sp. nov . Figs. 3 , 4 MycoBank no.: MB 829067 Type: CHINA . Yunnan Province , Puer, Jingdong county, Ailaoshan National Nature Reserve, on the angiosperm trunk, 4 October 2017 , CLZhao 4035 ( holotype , SWFC !) Etymolog y :— Yunnanensis (Lat.) : referring to the locality ( Yunnan Province ) of the type specimen. Description:— Basidiocarps annual, gregarious, without odor or taste and corky when fresh, becoming hard corky upon drying. Pilei spathulate to flabelliform, more or less stipitate, projecting up to 2 cm wide, 1 cm thick at centre. Pileal surface slightly tomentose, zonate, buff to ochraceous when fresh and ochraceous to pale brown upon drying. Hymenophore surface smooth, cream to buff when fresh, turn to buff to pale brown upon drying. Hyphal structure dimitic; generative hyphae with clamps, thin- to thick-walled, unbranched, 2.5–3.5 μm in diam.; skeletal hyphae colorless, thick-walled with a wide to narrow lumen, unbranched, 3–4.5 μm in diam.; IKI–, CB –, tissues unchanged in KOH. Hymenium :—Cystidia (caulocystidia) cylindrical with an apex or not, present in subiculum, thin- to thick-walled, 30–55 × 3–5 μm, cystidioles absent; basidia narrowly clavate to subcylindrical, with 4(2) sterigmata and a basal clamp, 25–32 × 2.5–4 μm; basidioles dominant, in shape similar to basidia, but slightly smaller. Basidiospores ellipsoid to subglobose, hyaline, thin-walled, smooth, IKI–, CB –, 3–3.5(–4) × 2.5–3(–3.5) μm, L = 3.34 μm, W = 2.71 μm, Q =1.2–1.31 (n = 120/4).
