During our investigation of diseases (2013-2018), a new leaf spot disease was found in seven provinces of China (Anhui, Fujian, Guangxi, Guizhou, Jiangxi, Tibet and Yunnan), occurring on both arboreal and terraced tea plants. The leaf spots were round to irregular, brown to dark brown, with grey or tangerine margins. Multi-locus (LSU, ITS, , , ) phylogenetic analyses combined with morphological observations revealed four new species belonging to the genus , , , and . Of these four species, was found to be present on diseased terraced tea plants in six of the seven sampled provinces (excluding Yunnan). The other three species only occurred on arboreal tea plants in Yunnan Province. In addition to the four species isolated from diseased leaves, . was isolated from healthy leaves of terraced tea plants.
在我们对病害的调查（2013 - 2018年）期间，在中国七个省份（安徽、福建、广西、贵州、江西、西藏和云南）发现了一种新的叶斑病，该病发生在乔木型和梯田型茶树植株上。叶斑圆形至不规则形，棕色至深棕色，边缘灰色或橘黄色。多位点（LSU、ITS等）系统发育分析结合形态学观察揭示了属于该属的四个新物种，分别为、、和。在这四个物种中，在七个采样省份中的六个（不包括云南）的患病梯田型茶树植株上发现了。其他三个物种仅出现在云南省的乔木型茶树上。除了从病叶中分离出的四个物种外，还从梯田型茶树的健康叶片中分离出了。
