03CBFA0FD213FFC0B4BAF9311ED4B0EE.taxon	diagnosis	Diagnosis: — H. xizangense differs from H. wellsiae by its relatively smaller pileus and unique geographical distribution, and differs from H. guldeniae by its larger and longer spores. Holotype: — CHINA. Tibet Autonomous Region, Linzhi City, Zayu County, on soil under mixed forests, 18 August 2021, A. G. Xu, holotype (SYAU-FUNGI- 080). Etymology: — The epithet ‘ xizangense ’ refers to the type location, ‘ Tibet’. Description: — Basidiomata small to medium. Pileus 4.5 – 6.0 cm broad, convex becoming plane and then slightly depressed at center, margin enrolled, light brown (5 B 2 – 3) to brown (5 C 4 – 7), towards centre with darker color, dry, margin striate. Lamellae short-decurrent, thin, moderately crowded, 2 – 3 tiers of lamellulae, undulating margin, light brown (5 B 3 – 4). Stipe 6.5 – 7.5 cm in length, about 0.8 – 1.0 cm in diam at the apex and up to 2.5 cm in diam at the base, central or somewhat eccentric, solid, subcylindrical to clavate, surface dry, longitudinally whitish-fibrillose with brown (5 C 4 – 7) background, abundant whitish mycelium. Context of pileus 2 – 4 mm thick, thinner at the margin, white. Odour faint, not distinct. Basidiospores (5.0 –) 5.5 – 6.5 (– 7.7) × 3.0 – 3.8 μm, Q = 1.40 – 2.20, Qm = 1.65, ellipsoid to elongate-ellipsoid, surface slightly coarse under the SEM. Basidia 26.5 – 36.5 × 3.8 – 5.8 μm, 4 - spored, with sterigmata 5.5 μm long, slightly amyloid. Cystidia absent. Hymenophoral trama regular, composed of cylindrical to inflated hyphae 5 – 10 μm wide. Pileipellis a cutis of radially arranged, inflated hyphae 5 – 12 μm wide, with intracellular yellow pigment. Stipitipellis composed of repent cylindrical hyphae 4 – 10 μm wide. Clamp connections absent in all parts of the basidiome. Habitat and distribution: — Solitary, on soil with rich humus, in montane coniferous forests, known from temperate zones of southwestern China; found during summer. Remarks: — Harmajaea xizangense is quite similar to H. guldeniae and H. wellsiae because they share a brownish pileus, decurrent lamellae, and a brownish stipe with a tomentose base. Geographically, H. guldeniae and H. wellsiae have been reported only from North America and Europe (Alvarado et al. 2018 b); while H. xizangense has been found only in Tibet, China. The other three Harmajaea species have pileus diameters of 5 – 16 cm (see Alvarado et al. 2018 b) whereas H. xizangense has a smaller pileus of 4 – 6 cm diameter. Furthermore, H. guldeniae has a spore size range of 4.3 – 5.1 × 3.0 – 3.8 μm, Q = 1.29 – 1.57, (see Alvarado et al. 2018 b) so the spores are smaller and shorter than those of H. xizangense (5.5 – 6.5 × 3.0 – 3.8 μm, Q = 1.40 – 2.20).	en	Qi, Yue, Yu, Xiao-Dan, Hou, Jian-Xuan, Guo, Hong-Bo, Yang, Rui-Heng, Xu, Ai-Guo (2024): Addition to the genus Harmajaea (Agaricales, Pseudoclitocybaceae): a new and a known species from China.

03CBFA0FD216FFC3B4BAFF5B1D25B119.taxon	description	Description: — Basidiomata medium to large. Pileus 3 – 11 cm broad, subglobose-hemispherical at first, then applanate, finally slightly depressed, margin enrolled, sometimes faintly wavy-lobed at maturity, smooth or minutely scaly, dry, pale yellow-orange to pale orange-yellow in color, cream-brown (5 C 3) to brown (5 C 3) at the centre. Lamellae crowded, 2 – 3 lamellulae tiers between each pair of entire lamellae, short-decurrent, thin, 1 – 2 mm broad, dirty white to pale brown. Stipe 0.7 – 2.3 cm in diam, 3.0 – 8.5 cm in length, central, cylindro-clavate, somewhat broadened towards the base, usually flexuous, fleshy, solid to loose, with rhizomorphs, longitudinally striped, concolorous with the pileus. Context 2 – 4 mm thick, thinner at the margin, white. Odour faint, not distinct. Spores (4.0 –) 4.5 – 5.5 (– 6.0) × (2.5 –) 3.0 – 3.7 μm, Q = 1.33 – 1.64 (Qm = 1.47), ellipsoid to amygdaliform, surface coarse under the SEM, slightly amyloid, not cyanophilous, not collapsing and not adhering in tetrads. Basidia 16.5 – 32.5 × 4.0 – 6.0 μm, 4 - spored, cylindro-clavate, with sterigmata 5 μm long, without carminophilic / siderophilous granulation. Cystidia absent. Hymenophoral trama regular, made up of cylindrical to inflated hyphae, 5 – 16 μm diam. Pileipellis a cutis of radially arranged, inflated hyphae, 5 – 12 μm diam, with intracellular yellow pigment. Stipitipellis composed of repent cylindrical hyphae, 4 – 10 μm diam. Clamp connections absent in all parts of the basidioma.
