Description.

see von Szilvinyi (1936).

Materials examined.

China, Anhui Province, Huangshan City, from diseased leaves of C. sinensis cv. Zhonghuang 1, 2 Jul 2019, Y. C. Wang, culture YCW 372 .

Notes.

Epicoccum tobaicum was synonymised as E. nigrum previously ( Hou et al. 2020 b). It was resurrected as a separate species, distant from E. nigrum ( Hou et al. 2020 b) . Conidia were globular to pear-shaped, dark, verrucose and multicellular ( Han et al. 2021). It formed a distinct lineage closely related to E. rosae (Fig. 3 ). This species as a pathogen was isolated from diseased leaves showing leaf spot of flowering cherry and oat ( Han et al. 2021; Jeong et al. 2022 a). In the present study, five strains were isolated from diseased tea plant leaves. This is the first report of E. tobaicum isolated from C. sinensis .

Figure 3. Phylogenetic tree generated by Maximum Likelihood analysis, based on the combined ITS, LSU, RPB 2 and TUB 2 dataset of Epicoccum species. Bootstrap support values above 50 % and Bayesian posterior values above 0.75 are shown at each node (ML / PP). Pleiochaeta setosa CBS 118.25 / CBS 496.63 and Co. palmarum CBS 400.71 are used as outgroups. Ex-type strains are emphasised in bold.
