Abstract: Diaporthe sackstonii R. G. Shivas, S. M. Thomps. & Y. P. Tan, Persoonia 35: 46 (2015) Suppl. material 7 Material examined. China • Beijing City, Haidian District, JiuFeng forest farm, from branches of J. regia, M. Li, L. L. Zhao and L. Zhang, 26 August 2022 (2022-JF-34, culture CGMCC 3.28287, CGMCC 3.28295, CGMCC 3.28297). Notes. Diaporthe sackstonii was first described from Helianthus annuus in Australia (Thompson et al. 2015). Pereira and Phillips (2024) treated D. caryae, D. machili, D. juglandigena, and D. orixae as the synonyms of D. sackstonii. Phylogenetically, three isolates clustered together with D. sackstonii (Fig. 5); the base pair similarity shows 97.5 % (466 / 478) on his, 99.2 % (506 / 510) on ITS, 98.1 % (370 / 377) on tef 1 - α, and 98.6 % (488 / 495) on tub 2 compared to the ex-type of D. sackstonii. Morphologically, the alpha conidia are similar to D. sackstonii (5–7.5 × 2.5–3.5 vs. 6–7 × 2–2.5) (Table 1) (Thompson et al. 2015). In this study, D. sackstonii was collected from the walnut plantation of Beijing. This collection is the first report of D. sackstonii occurring on J. regia.
