Materials examined.

China • Jilin Province, Yanbian Korean Autonomous Prefecture, Yanji City, Maoershan National Forest (42°51'12.96"N, 129°28'24.06"E), alt. 297 m, on branches of Larix olgensis, 7, Sept, 2022, C. Peng, X. Y. Zhang (BJFC - S 2374, living culture CFCC 70812, CFCC 70813) .

Notes.

Phaeobotryon rhois was first discovered and reported on Rhus typhina (Fan et al. 2015) . This species has also been isolated from diseased branches of the hosts Dioscorea nipponica, Platycladus orientalis, and Rhamnus davurica (Pan et al. 2019), as well as from Populus alba var. pyramidalis (Lin et al. 2023) . Morphologically, its asexual morph (Fig. 5) aligns with the description provided by Fan et al. (2015). Phylogenetically, the isolates CFCC 70812 and CFCC 70813 clustered within a clade alongside P. rhois, demonstrating high statistical support (MP / ML / BI = 96 / 99 / 0.99) (Fig. 1). The current study expands its host range to include L. olgensis .
