M. He & Y. Z. Yang 2025	<div><p>Ripartites subtropicus Z.M. He &amp; Y.Z. Yang, sp. nov. (Figs. 2–4)</p><p>MycoBank: MB857719</p><p>Etymology:— ‘ subtropicus ’ (Latin), referring to the subtropical habitat.</p><p>Diagnosis:—This species has a white to light brown depressed pileus with finely pubescent margin, cream decurrent lamellae, a yellow-brown stipe with basal rhizoids, and verrucose basidiospores. Similar to R. tricholoma, but differs by its nearly naked to indistinct pubescent pileus margin, the concurrent presence of mono-, bi- and tetrasporic basidia, and its subtropical habitat.</p><p>Type:— CHINA. Guizhou Province: Shuicheng County, Shuicheng National Rhododendron Garden, on humus covered with needle litter of Pinus armandii Franch., alt. 1982 m, at 26°47'34.82''N, 104°49'4.63''E, 17 June 2023, Z.M. He 1, MHHNU 20001 (holotype!).</p><p>Description:— Fruitbody small-sized, omphalioid. Pileus 10–30 mm in diam, applanate to slightly depressed with an unconspicuous papilla at center, hygrophanous; surface white (1A1) when dry, light brown (3A2–3) when wet, yellowish brown (5A2–4) at center, smooth, not gelatinized; margin inflexed to involute when young, straight when old, finely white (1A1) pubescent at very margin, not striate; context thin (1–2 mm thick), white (1A1). Lamellae decurrent, subcrowded, sometimes furcate near stipe apex, arcuate, cream (1A2), narrow (1–2 mm high); edges even. Stipe 14–35 × 2–3 mm, central or somewhat eccentric, solid, equal, often flexuous; surface wet, yellow-brown (3B4– 6), finely white-fibrillose longitudinally; base not inflated, with white (1A1) rhizomorphs; context white (1A1). Odor fungoid and pleasant. Chemical spot test: surface of dried pileus and stipe produces a negative reaction to 30% KOH.</p><p>Basidiospores [100/3/3] (4–)4.5–5.5 × 4–5 μm, Q = (1.02–)1.04–1.23(–1.28), Qm = 1.13 ± 0.06, pale brown, subglobose to broadly ellipsoid, with verrucae 0.4–0.6 × 0.3–0.4 μm, thin-walled, inamyloid. Basidia 20–27 × 6–9 μm, clavate, hyaline, thin-walled, 1-, 2- or 4-spored; sterigmata up to 9 μm long. Pleurocystidia and cheilocystidia absent. Lamellar trama subregular, composed of thin-walled, cylindrical, non-branched hyphae 4–10 µm wide. Pileipellis a cutis, composed of parallel to slightly interwoven, thin-walled, cylindrical hyphae 3–6 μm wide, with clusters of filamentous hyphae at margin. Stipitipellis a cutis, composed of parallel, thin-walled hyphae 4–8 μm wide. Clamp connections present in all tissues.</p><p>Ecology:—Solitary, on humus, in subtropical montane forests; summer.</p><p>Distribution:—Only known from Southwestern and Central China.</p><p>Additional specimens examined:— CHINA. Hubei Province: Qingchuan County, southern district of Shennongjia Forestry, on humus covered with oak leaf litter, alt. 1800 m, at 31°24'54.14''N, 110°29'58.53''E, 16 July 2012, J. Qin 555, KUN-HKAS 77956. Guizhou Province: Leishan County, Leigong Mountain National Forest Park, on humus covered with leaf litter of Pinus fenzeliana Hand.-Mazz and Fagus sp., alt. 1730 m, at 26°22'36.81''N, 108°11'58.19''E, 21 June 2023, Z.M.
