G. Zheng, (ML 7 = GMB-W 1508). Pileus 23 – 38 mm in diameter, parabolic or plane when young and convex-subumbonate when mature, slightly hygrophanous, bronze brown (5 E 5) to yellowish brown (5 E 4) at the center and brownish grey (5 E 2) to birch grey (5 C 2) towards the margin, forming a straight and regular margin. Veil white (5 A 1), fibrillose, rarely on the edge of the pileus, and gradually disappearing in maturity stages. Lamellae adnate to slightly adnexed, greyish red (10 C 4) to reddish grey (10 B 2). Stipe 44 – 87 × 3 – 5 mm, cylindrical, hollow, equal, slightly flexuous, white (5 A 1) to white grey (5 B 1), with a little white mycelium at the base. Annulus absent. Odour and taste were not determined. Basidiospores (5.2 –) 5.3 – 7.0 (– 7.4) × (2.8 –) 3.0 – 4.3 (– 4.4) µm (avL = 6.22 µm, avW = 3.68 µm), Q = 1.45 – 2.05, Q m = 1.70, ellipsoid to oblong, pale brown to brown in water, and deepens in 5 % KOH, smooth, with small germ pore. Basidia (15.8 –) 16.3 – 25.3 (– 28.0) × (5.5 –) 5.8 – 8.4 (– 8.6) µm, short clavate, hyaline, 4 - spored, a few 2 - spored, rarely unisterigmate, with granular content, in front view elliptic to oval, in side view adaxially flattened to slightly subphaseoliform. Cheilocystidia (27.9 –) 28.5 – 49.9 (– 51.4) × (7.0 –) 8.5 – 15.7 (– 16.1) µm, narrowly utriform, cylindrical to claviform, thin-walled, rarely with deposits, lageniform top, conical, hyaline. Pleurocystidia absent. Pileipellis a one to two-layered irregular epithelium composed of globose to subglobose or ellipsoid cells with 43 – 70 × 35 – 54 µm diameter, thinwalled, hyaline in 5 % KOH. Clamp connection present. Habitat: Scattered on the soil, among grasses and fallen leaves.	en	Zheng, De-Ge, Voto, Pietro, Tibpromma, Saowaluck, Lu, Wen-Hua, Han, Mei-Yan, Kumla, Jaturong, Suwannarach, Nakarin, Dai, Dong-Qin, Zhang, Li-Juan, Elgorban, Abdallah M., Chukeatirote, Ekachai, Karunarathna, Samantha C.

03E8E315930DFF8FFF43FCE71DADF7DD.taxon	distribution	Distribution: Only known from Yunnan, China. Additional specimen examined: China, Yunnan Province, Qujing City, Malong County, 25 ° 25 ′ 28 ′′ N 103 ° 28 ′ 49 ′′ E, elev. 1,973 m, 13 June 2024, S. C. Karunarathna, (QJ 345 = GMB-W 1509, paratype). GenBank numbers: GMB-W 1508: nrITS = PV 590303, nrLSU = PV 618426, tef - 1 α = PV 640648.

03E8E315930DFF8FFF43FCE71DADF7DD.taxon	description	Notes: In morphology, C. yunnanensis differs from C. shennongdingicus by longer stipes (44 – 87 × 3 – 5 mm vs. 34 – 53 × 3 – 5 mm), slightly smaller basidiospores and basidia, bigger cheilocystidia (28.5 – 49.9 × 8.5 – 15.7 µm vs. 29.8 – 40.5 × 9.5 – 13.3 µm), and, especially, larger pileipellis cells (43 – 70 µm vs. 19.8 – 29.5 µm). Candolleomyces shennongdingicus has a different color with pileus which is golden yellow (5 B 7) to golden brown (5 D 7) at the center and golden blonde (5 C 4) to nougat (5 D 3) toward the margin, and the lamellae are orange-grey (5 B 2) to grey (5 D 1). In addition, although both our collection and C. shennongdingicus are from China, C. shennongdingicus is found on the ground with rich humus in broad-leaved or deciduous coniferous forests in Hubei Province (Han et al. 2024), while our collection was from the grassland of a deciduous broad-leaved forest in Yunnan Province. Based on this evidence, we identify our collection as C. yunnanensis sp. nov.	en	Zheng, De-Ge, Voto, Pietro, Tibpromma, Saowaluck, Lu, Wen-Hua, Han, Mei-Yan, Kumla, Jaturong, Suwannarach, Nakarin, Dai, Dong-Qin, Zhang, Li-Juan, Elgorban, Abdallah M., Chukeatirote, Ekachai, Karunarathna, Samantha C.
