“…Conidia produced by E. poaceicola were ellipsoidal to cylindrical and sometimes with small guttules ( Thambugala et al 2017 ). Epicoccum poaceicola can cause leaf spot in bamboo, camphor tree and eggplant ( Liu et al 2020 ; Li et al 2022 ; Aementado and Balendres 2023 ). In the present study, seven strains were isolated from healthy tea plant leaves.…”

Tea plant is one of the most important commercial crops worldwide. The Didymellaceae fungi can cause leaf blight disease of tea plant. In this study, 240 isolates were isolated from tea plant leaves of 10 provinces in China. Combined with multi-locus (ITS, LSU, RPB2 and TUB2) phylogenetic analysis and morphological characteristics, these isolates were identified as 25 species of six genera in Didymellaceae, including 19 known species Didymella coffeae-arabicae, D. pomorum, D. segeticola, D. sinensis, Epicoccum catenisporum, E. dendrobii, E. draconis, E. italicum, E. latusicollum, E. mackenziei, E. oryzae, E. poaceicola, E. rosae, E. sorghinum, E. tobaicum, Neoascochyta mortariensis, Paraboeremia litseae, Remotididymella anemophila and Stagonosporopsis caricae, of which 15 species were new record species and six novel species, named D. yunnanensis, E. anhuiense, E. jingdongense, E. puerense, N. yunnanensis and N. zhejiangensis. Amongst all isolates, D. segeticola was the most dominant species. Pathogenicity tests on tea plant leaves showed that E. anhuiense had the strongest virulence, while E. puerense had the weakest virulence. Besides, D. pomorum, D. yunnanensis, E. dendrobii, E. italicum, E. jingdongense, E. mackenziei, E. oryzae, E. rosae, E. tobaicum, N. mortariensis, N. yunnanensis, N. zhejiangensis and R. anemophila were non-pathogenic to the tea plant.
