Description.

see Valenzuela-Lopez et al. (2018).

Materials examined.

China, Jiangxi Province, Nanchang City, from diseased leaves of C. sinensis cv. Zhenong 139, 22 Jun 2019, Y. C. Wang, culture YCW 142 .

Notes.

Epicoccum catenisporum was introduced as Phoma catenisporum before the comprehensive revision of Epicoccum ( Chen et al. 2015 a) . It was first isolated from a leaf spot of Oryza sativa in Guinea-Bissau and morphologically characterised by the production of pycnidia as observed in several other members of Epicoccum ( Valenzuela-Lopez et al. 2018) . Conidiogenous cells were phialidic, hyaline, doliiform or ampulliform and conidia were aseptate, hyaline ovoid or ellipsoidal and guttulate ( Valenzuela-Lopez et al. 2018). In the present study, one isolate from diseased tea plant leaves grouped with E. catenisporum ( CBS 181.80) with high statistical support (Fig. 3 ). This is the first report of E. catenisporum isolated from C. sinensis .

Figures

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.
