Basidia (18 –) 20 – 40 (– 45) × 3 – 5 (– 6) μm, clavate, clamped; contents homogeneous when young, slightly grainy, hyaline or slightly yellowish, slightly cyanophilous, 4 - spored. Hyphal system septate, branching, agglutinated with crystalline contents, monomitic, and with septate generative hyphae; tramal hyphae of branches (1.8) 2 – 5 μm wide, narrow to thick-walled, branching, parallel, and compactly organized. Clamp connections are present.	en	Zheng, De-Ge, Lu, Wen-Hua, Han, Mei-Yan, Elgorban, Abdallah M., Yang, Jing-Ya, Zhou, Yuan-Qing, Suwannarach, Nakarin, Tibpromma, Saowaluck, Karunarathna, Samantha C.

6738AD74FFE6625BCEEAFD41864661D6.taxon	discussion	Notes: In phylogenetic analyses (Figure 1), our new collections of P. yunnanensis were well-separated from P. carovinacea specimens (AMB 18533, AMB 18534, AMB 18551, TUR-A- 209584) with 58 % BS and 0.95 PP statistical support. Morphologically, P. yunnanensis differs from P. carovinacea by having smaller basidiomata (30 – 60 × 10 – 20 mm vs. 50 – 70 × 20 – 30 mm), longer stipe (8 – 40 vs. 30 mm), connections of branches are reddish yellow to light yellow, base part light yellow, smaller basidia (20 – 40 × 3 – 5 mm vs. 28 – 40 × 5 – 7 mm), and narrower hyphae branches (2 – 5 μm vs. 8 – 10 μm). In addition, P. yunnanensis is similar to P. jilinensis which was reported in China (MHHNU 10504) (Deng et al. 2024). Phaeoclavulina yunnanensis differs from P. jilinensis by having reddish-yellow to light yellow, smaller basidiomata (30 – 60 × 10 – 20 mm vs. 35 – 90 × 15 – 50 mm), verrucose, smaller basidiospores (4 – 6 × 2 – 3.5 μm vs. 6 – 8 × 3 – 5 μm), polychotomous, blunt sharp spines, smooth and gelatinous at the top of branches (Deng et al. 2024). However, the phylogenetic analysis indicates that P. yunnanensis and P. jilinensis are clustered in different clades (Figure 1). Therefore, in this study, P. yunnanensis is introduced as a new species based on morphological and molecular evidence.	en	Zheng, De-Ge, Lu, Wen-Hua, Han, Mei-Yan, Elgorban, Abdallah M., Yang, Jing-Ya, Zhou, Yuan-Qing, Suwannarach, Nakarin, Tibpromma, Saowaluck, Karunarathna, Samantha C.
