0C4ADC0FFFD1FFD8AAD19DAEFD712B01.taxon	etymology	Etymology: Named from “ Populus ”, in reference to the host genus. Description: Infected branches nearly circular, blister-like lesions around the lenticels in the early stage. Subsequently, the lesions dehydrate and shrivel, forming circular, slightly sunken, dark brown necrotic spots. The sexual morph was not observed. Conidiomata pycnidial globose, stromatic, immersed, sometimes superficial, solitary or aggregated, dark brown to black. Conidiogenous cells hyaline, thin-walled, smooth, cylindrical, swollen at the base, discrete, and produce a single conidium at the tip (FIGURE 2). Conidia oblong, clavate to elliptical, with a blunt apex and a thick, smooth wall, aseptate, 20.9 – 23.5 μm × 8 – 10.5 μm (mean SD = 22.4 ± 0.7 × 8.9 ± 0.8 μm, n = 30, L / W = 2.4) in size, appearing hyaline to yellowish, became dark brown when released (FIGURE 2). Culture characteristics: The average diameters of colonies on PDA were 85 mm, respectively, after three days of dark incubation at 24 ° C. The mycelium developed circular colonies, initially white and cotton-like. After a seven-day incubation period at 24 ° C, the colonies turned black, with some hyphae becoming aerial (FIGURE 2).	en	Zhang, Zhe, Jiao, Ning, Guo, Lin-Na, Wang, Jia-Wen, Zhang, Ying (2025): Diplodia populicola sp. nov. causing branch canker of poplar in Beijing, China.

Zhang, N. Jiao and Y. Zhang (holotype WYHD 7 - 1; ex-type living culture CGMCC 3.28774). CHINA, Beijing, Changping District, Wenyuhe Park (40 ° 07 ’ 33.9 ” N, 116 ° 22 ’ 17.5 ” E), from branches of poplar, 23 September 2023, Z. Zhang, N. Jiao and Y. Zhang (paratype WYHD 7 - 2; living culture CGMCC 3.28775). Notes: A combination of morphological characteristics and multi-gene phylogenetic analyses based on ITS, tef 1 - α, and tub 2 loci provided evidence for its classification. Phylogenetic analysis demonstrated that D. populicola formed a distinct lineage clustering with D. seriata and its close relatives, yet with a clearly separate branch, supporting its designation as a novel species. The tef 1 - α marker is regarded as one of the most informative for distinguishing species within the Botryosphaeriaceae. Morphologically, D. populicola resembles its close relative D. seriata (Phillips et al. 2013), but has smaller conidia (20.9 – 23.5 × 8 – 10.5 vs. 21.5 – 28 × 11 – 15.5 μm) and exhibits a higher length-to-width ratio compared to D. seriata (L / W = 2.4 vs. 1.9).	en	Zhang, Zhe, Jiao, Ning, Guo, Lin-Na, Wang, Jia-Wen, Zhang, Ying (2025): Diplodia populicola sp. nov. causing branch canker of poplar in Beijing, China.
