Notes.

Diaporthe rostrata was first described from Juglans mandshurica in Gansu Province, China ( Fan et al. 2015). Dissanayake et al. (2024) compared morphological details and phylogenetic analysis, treating D. juglandicola as the synonym of D. rostrata . Phylogenetically, four isolates clustered together with D. rostrata with high support (100 % / 1 / 100 %) (Fig. 2 View Figure 2 ); the base pair similarity shows 99.6 % (455 / 457) on cal, 98.2 % (439 / 447) on his, 100 % (550 / 550) on ITS, 99.2 % (357 / 360) on tef 1 - α, and 100 % (473 / 473) on tub 2 compared to the ex-type of D. rostrata . Morphologically, the culture characteristics and alpha conidia are consistent with the description of D. rostrata (Table 1 View Table 1 ) ( Fan et al. 2015). In this study, D. rostrata was collected from the walnut plantations of Beijing, Gansu, Hebei, Shandong, Shanxi, and Yunnan provinces.
