Zhang, 14 December 2021 (2021-JF-6, culture CGMCC 3.28277; CGMCC 3.28281; 2021-JF-10, culture CGMCC 3.28282, CGMCC 3.28284). • Shanxi Province, Jiaokou City, from diseased branches of J. regia, Y. Ding, M. Li and L. L. Zhao, 28 February (JK-4, culture CGMCC 3.28276). • Yunnan Province, Kunming City, from diseased branches of J. regia, Y. Ding, M. Li and L. L. Zhao, 23 February 2024 (YN-23, culture CGMCC 3.28290). • Shandong Province, Liaocheng City, from diseased branches of J. regia, Y. Ding, M. Li and L. L. Zhao, 5 February 2024 (LC-12, culture CGMCC 3.28280). • Hebei Province, Chengde City, from diseased branches of J. regia, Y. Ding, M. Li and L. L. Zhao, 13 February 2024 (CD-3, culture CGMCC 3.28298). Notes. Diaporthe eres was first described by Nitschke (1870) and collected from Ulmus sp. in Germany. It has a wide distribution and a broad host range as a pathogen, endophyte, or saprobe, and can cause a variety of plant diseases (Udayanga et al. 2014). Hilário et al. (2021 b) and Dissanayake et al. (2024) identified the D. eres complex as a single species, D. eres. Phylogenetically, eight isolates clustered within D. eres (Fig. 3). Therefore, these isolates were confirmed to belong to D. eres, based on sequence data and morphology (Table 1). In this study, more than half of the isolates (189, 67.5 %) belong to D. eres, which is nationally distributed in Beijing, Gansu, Hebei, Shandong, Shanxi, and Yunnan, causing walnut branch diseases.
