Notes: — Cudonia gracilistipitata was described by Hyde et al. (2024) and is reported for the first time in Yunnan. In this study, this species characterized by saddle-shaped, grey pileus with a gradually thinning margin and elongated and thinner stipes.

Paraphyses 1.6 – 3.7 μm (x = 2.3 μm, n = 13) in diameter, hyaline, long and narrow strips, unbranched, aseptate, rounded ends. Asci 77 – 148 × 8.2 – 15.8 μm (x = 120 × 12.3 μm, n = 50), 8 - spored, hyaline, inamyloid, inoperculate, clavate to narrowly clavate, pleurorhynchous, prototunicate, gradually narrows towards the base.

Additional specimen examined: — CHINA, Yunnan Province, Dali Bai Autonomous Prefecture, Cangshan mountain, surface of the coniferous forest soil, 2,122 m, Song-Ming Tang and Kai-Yang Niu, 27 October 2024 (HKAS 147015). Notes: — In the phylogenetic analysis, Cudonia cangshanensis and C. lutea form sister clades. Sequence comparison for the ITS region between C. cangshanensis (HKAS 147014 holotype) and C. lutea (Z. W. Ge 608) showed a 3.77 % (16 / 424 bp, excluding gaps) base pair difference. Cudonia lutea differs from C. cangshanensis by pileus pileate, fleshcolor to orange-buff, narrow ascospores (2 μm), without ascoconidia. In morphology, Cudonia cangshanensis and C. yunnanensis share similar characteristics in the pileus are both saddle-shaped, with brown stipes that slightly swollen at the base. However, there are distinct differences in microscopic morphology, the hymenium (x = 154 µm), asci (x = 112 × 10.8 µm), ascospores (x = 55 × 2.2 µm), and paraphyses (x = 2.1 µm) of C. yunnanensi s are smaller than those of C. cangshanensis (TABLE 2).	en	Niu, Kai-Yang, Yu, Feng-Ming, Tang, Song-Ming, Li, Lin, Luo, Zong-Long (2025): Morphological characteristics and phylogenetic analysis reveal a new species of Cudonia (Cudoniaceae, Rhytismatales) from Yunnan, China.
