165A87EEFFB0FFCCFF1EF8EB43ECE3B5.taxon	etymology	Etymology: — griseo, grey, clavus, clavate, referring to the color and shape of the basidiomata. Holotype: — CHINA. Shanxi Province, Pangquangou National Forest Park, 37 ° 49 ʹ 5 ʺN, 111 ° 28 ʹ 34 ʺE, 1800 m, 29 August 2018, on soil among decomposing litter under the mixed forest dominated by Pinus tabuliformis and Quercus wutaishanica, J. Yang LH 286 A (BJTC FM 964). Description: — Basidiomata 70 – 130 × 10 – 15 mm, subcylindric to clavate, slightly tapering downward, apex obtuse, surface smooth when young, rugose to rugulose at maturity, color of the upper part grey-white when young, grey to greyish at maturity, grey-white to pale white towards base. Basidia 87.5 – 132.5 μm in length, thin-walled, narrowly clavate to clavate, apically inflated at maturity, becoming broadly clavate, 10 – 17.5 μm diam, basal clamp connections present, tetrasterigmate, sterigmata (5 –) 7.5 – 10 (– 12.5) μm in length. Basidiospores 10 – 11 × 5 – 6.5 μm, Q (L / I) = 1.33 – 2.10 (Qm = 1.89) (n = 60), ellipsoid to narrowly ellipsoid, smooth, thin-walled, inamyloid, with a prominent apiculus, hyaline in KOH and lightly staining in Congo Red. Leptocystidia 75 – 112 × 2.5 – 6 μm, mixed among the basidia, scarcely projecting beyond the basidia, cylindrical, subcylindrical, strangulated, flexuous, sometimes apically branched, or inflated, occasionally with inclusions. Basal clamp connections present. Context hyphae 5 – 11 μm diam, parallel, septate, rarely inflated, hyaline in KOH. Habit, habitat and distribution: — Epigeous, on soil among decomposing litter in mixed forest dominated by P. tabuliformis and Q. wutaishanica, Shanxi Province, China. Additional specimens examined: — CHINA.
