Description.

see Chen 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 YCW 2005 .

Notes.

Phylogenetically, Epicoccum italicum formed a distinct lineage closely related to E. oryzae (Fig. 3 ). Epicoccum italicum produced epicoccoid conidia and clavate conidiomata ( Chen et al. 2017). It was first isolated from seedlings of Acca sellowiana in Italy ( Chen et al. 2017) and reported in the dairy setting ( Rodríguez et al. 2023). In addition, this species significantly reduced both leaf area of soybean consumed aboveground by caterpillars and number of cysts produced belowground by nematodes ( Rivera-Vega et al. 2022). In the present study, one strain was isolated from healthy tea plant leaves. This is the first report of E. italicum isolated from C. sinensis .

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.
