Recent advances in taxonomy have led to the need to conduct fresh surveys of species associated with important crops. Anthracnose caused by spp. is one of the destructive diseases on . In this study, a total of 22 representative isolates were obtained from diseased leaves of cultivated in four tea plantation regions in Anhui Province of China. The isolates were identified based on multilocus (, , , , , ) phylogenetic analyses, and their morphological characteristics were also analyzed. Twenty-one isolates belonging to complex were identified as , , and . One isolate belonging to complex was identified as . Pathogenicity tests revealed that the isolates of and were highly virulent when inoculated on the leaves of detached twigs of cv. Shuchazao. Furthermore, it was found that the interspecies virulence was less distinct and individual isolates showed varied virulence when inoculated on different varieties of . To our knowledge, this is the first report of , , and causing anthracnose on in Anhui Province, China.
最近的分类学进展使得有必要对与重要作物相关的物种进行新的调查。由 spp.引起的炭疽病是对的一种破坏性疾病。在这项研究中，从中国安徽省四个茶园种植的患病叶片中总共获得了 22 个有代表性的分离株。根据多位点（、、、、、）系统发育分析对分离株进行了鉴定，同时还分析了它们的形态特征。属于 复合体的 21 个分离株被鉴定为 、和 。属于 复合体的一个分离株被鉴定为 。致病性试验表明，当接种到离体小枝叶片上时，和 的分离株具有高致病性。此外，还发现种间毒力不明显，当接种到不同品种的上时，个别分离株表现出不同的毒力。据我们所知，这是首次在中国安徽报道 、和 引起的炭疽病。
