            <p> Porotheleum microsporum P. M. Wang, Z. B. Huang, Y. Q. Wei &amp; J. X. Shen ,  sp. nov. (Fig. 2) </p>
            <p>MycoBank no.: MB 853453</p>
            <p> Etymology:—the epithet,  microsporum , refers to the small basidiospores compared to those of the other  Porotheleum species described so far. </p>
            <p>  Type:— CHINA. Shandong Province: Ji’nan City,  Quancheng Park , on the trunk of  Salix babylonica L., elev. 47 m, 4 September 2023, P. M. Wang 219A (EFHAAU10566, holotype!). [GenBank accession numbers—ITS: PP576323, LSU: PP576335; all from holotype]  . </p>
            <p> Description:—Basidiomata (Fig. 2a) on the trunk of  Salix babylonica . Pileus small, omphalinoid, (3) 5–20 (2.5) mm diam., convex to applanate at first, then planoconvex with the centre depressed; surface smooth, greasy; center pale ochre-yellow (5A3–5C3), elsewhere yellowish (5A1–5A2), or pale-yellow (4A1–4A2), subviscid to viscid when wet; transparently sulcate when moist, slightly translucently furrowed to the centre, involute. Lamellae cream to yellowish white (2A2); edge even, thick, distant, at the bottom slightly intervenose, decurrent, with interspersed lamellulae of various lengths. </p>
            <p>Stipe central, (2) 5–18 (29) × 0.5–2 (2.5) mm, cylindrical to tapering upwards, near lamellae pale-yellow (5A2), basal part reddish-brown (5E2) to dull dark (red-) brown (5E6); surface not viscid. Context thin, whitish to pale-yellow (4A1–4A2). Odour non-distinctive, taste mild.</p>
            <p>Basidiospores (Fig. 2b) [82/10/4] (4.4) 4.8–7.4 (7.75) × (2.6) 3.0–4.5 (4.8) μm (X = 6.1 ± 0.80 × 4 ± 0.47 μm), Q = (1.23) 1.33–1.85 (1.93), (Q m = 1.53 ± 0.15), ellipsoid, smooth, thin-walled, hyaline, cyanophilic, congophilic, nonamyloid. Basidia (Fig. 2d) 16–40 × 4.5–7 μm, narrowly clavate, thin-walled, 2-spored, long claviform, sterigmata up to 6 μm long. Hymenial cystidia absent. Hymenophoral trama composed of colourless, thin-walled cylindrical filamentous hyphae, 3–10.5 μm wide. Pileipellis (Fig. 2c), a cutis composed of wide hyphae, 3.5–7.5 (9) μm wide., slightly thick-walled, subcylindrical to fusiform, brownish, brown to yellow tawny, pileocystidia absent. Subcutis consists of colourless, thin-walled, subcylindrical to fusiform, 6–13.5 μm wide, with scattered small crystals. Stipitipellis (Fig. 2e) a trichoderm composed of caulocystidia and hyphidia; caulocystidia (Fig. 2f) narrowly lageniform, narrowly fusiform or narrowly conical, fusoid-lanceolate, yellow-brown, thick-walled, 10–40 × 4–8 μm; hyphidia abundant, thin-walled, unbranched, 2–5 μm wide. Clamp connections present in all parts of basidiomata.</p>
            <p> Habitat (Ecology):—Ecology saprobic;   growing alone or gregariously on the trunks of  Salix babylonica distributed in  Quancheng Park (Ji’nan City, Shangdong Province, China) at an elevation of 47m. </p>
            <p>Distribution:—currently known only from Quancheng Park in Ji’nan City.</p>
            <p> Additional specimens examined:   CHINA. Shandong Province: Ji’nan City, Quancheng Park, on the trunk of  Salix babylonica , elev. 47 m, 4 September 2022, P. M. Wang 219B (EFHAAU10567! [  GenBank accession numbers—ITS: PP576324, LSU: PP576336]; same location, 4 September 2022, P. M. Wang 219C (EFHAAU10568!) and P. M. Wang 219D (EFHAAU10569!). </p>
            <p> Remarks:—It differs from the other similar species by its small-sized basidiomata on the trunk of  Salix babylonica , yellowish pileus with a center pale ochre-yellow, and relatively small basidiospores. </p>
