Figs. 1–2</p><p>Fungal Names number: FN 571979</p><p>Etymology: —From Latin, “pseudo” means similar to; pseudoandrosaceus refers to the new species’ resemblance to G. androsaceus .</p><p>Holotype: — CHINA. Guizhou, Zunyi City, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=107.26972&amp;materialsCitation.latitude=28.526945" title="Search Plazi for locations around (long 107.26972/lat 28.526945)">Fuyan Town</a>, 107°16′11″E, 28°31′37″N, elev. 1397.96 m, fallen twigs of a broadleaved tree, 10 May 2023, LHF1475 (HGASMF01-23515).</p><p>Diagnosis:—Characterized by the marasmioid basidiomata, brown pileus and lamellae colors, striate pileus, adnate to subdistant lamellae, black stipe, well-developed rhizomorphs, repent pileipellis hyphae and diverticulate cheilocystidia. Differs from Gymnopus androsaceus in having a shining black stipe and robust rhizomorphs, narrow, thick, and crowded lamellae; a cutis pileipellis without broom cells and with encrusting brown pigments.</p><p>Description:—Pileus 8–15 mm diam, broadly convex, expanding to plano-convex, striatulate; membranous, surface dull, dry, velutinous, brownish orange (6D6,7D 8,7E 8) with a dark, light brown to dark brown (7F8) umbo. Context 0.5 mm thick, brown. Lamellae adnexed to shallowly adnate, crowded (L = 24–35), lamellulae l = 4–5, narrow (1–1.5 mm), sometimes forked or anastomosing, light brown (6D6,7D8), non-marginate, concolorous with pileus. Stipe 7–14 × 0.5–1 mm, central, cylindrical, filiform, horse-hair like, tough, smooth, glabrous, insititious, dark brown (7F8), arising from woody substrates or directly from rhizomorphs. Rhizomorphs black, glabrous, common, long, branched or unbranched, 0.5‒1 mm thick. Odor indistinct.</p><p>Basidiospores 6.4–9.8(–10.9) × (3.0‒) 3.1–4.7(‒5.0) μm (average = 8.13 × 3.63 μm, E = (1.84–)1.87–2.55(‒2.78), Qm = 2.23±0.20), ellipsoid to oblong, inamyloid, hyaline. Basidia (20)24.5–37(‒38.2) × 5–7.6(‒9) μm, 2- or 4-spored, clavate, cylindrical. Basidioles 20.8–34(‒36) × (3.5‒)4.5–6.8(‒8) μm, fusiform, clavate, cylindrical. Cheilocystidia (8‒)10–38 × 2.5–9(‒10) μm, irregularly clavate, lobed to irregularly branched, with conical or apical projections. Pleurocystidia absent. Pileipellis a cutis of encrusted hyphae, sometimes with some lobed structures, 4–8 μm broad, broom cells not found. Stipitipellis a cutis composed of cylindrical, thin-walled, hyaline, parallel-arranged hyphae, dextrinoid, smooth. Caulocystidia absent. Clamp connections present in all tissues.</p><p>The mycelium was isolated from the fruiting bodies. The purified culture consists of white hyphae. Hyphae growth rate was nearly 1 cm. d-1, the plate showed the mycelium growing on the fifth day.</p><p>Ecology: —Saprotrophic, gregarious, usually arising on dead twigs or branches in broadleaf forests.</p><p>Additional specimens examined:— CHINA.
