Abstract: Diaporthe citrichinensis F. Huang, K. D. Hyde & H. Y. Li, Fungal Divers 61: 247 (2013) Suppl. material 3 Specimens examined. China • Yunnan Province, Kunming City, from diseased branches of J. regia, Y. Ding, M. Li and L. L. Zhao, 23 February 2024 (YN-7, culture CGMCC 3.27759; YN-26, culture CGMCC 3.27753). Notes. Diaporthe citrichinensis was first described from decaying wood of Citrus unshiu in China (Huang et al. 2013). Dissanayake et al. (2024) treated Diaporthe acerigena, D. albosinensis, D. coryli, D. fraxinicola, D. tibetensis, and D. ukurunduensis as the synonyms of D. citrichinensis. Phylogenetically, two isolates clustered together with D. citrichinensis with high support (100 % / 1 / 100 %) (Fig. 3); the base pair similarity shows 100 % (471 / 471) on cal, 97.7 % (434 / 444) on his, 100 % (530 / 530) on ITS, 100 % (333 / 333) on tef 1 - α, and 100 % (480 / 480) on tub 2 compared to the ex-type of D. citrichinensis. Morphologically, alpha and beta conidia are similar to D. citrichinensis (6.0–10.0 × 1.5–3.0 vs. 5.5–9 × 1.5–2.5 μm) and (32–44 × 1–2 vs. 27.5–40 × 1–1.5 μm) (Table 1) (Huang et al. 2013). In this study, D. citrichinensis was collected from the walnut plantation of Yunnan. This is the first report of D. citrichinensis occurring on J. regia.
