Description.

see Jayasiri et al. (2017).

Materials examined.

China, Yunnan Province, Puer City, Jingdong Yizu Autonomous County, from healthy leaves of C. sinensis , 13 Jun 2020, Y. C. Wang, culture ex-type CGMCC 3.24244 = YCW 1965 and culture ex-type CGMCC 3.24245 = YCW 1967 .

Notes.

Epicoccum mackenziei formed a distinct clade basal to E. endophyticum (Fig. 3 ). It was found as the sexual morph in nature and as chlamydospores in culture. Zhang et al. (2023) first reported that E. mackenziei caused dark brown spot of tea leaf in China. In the present study, two strains were isolated from healthy tea plant leaves.

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.
