species are significant pathogens of various economic plant hosts worldwide. In this study, 45 isolates were obtained from symptomatic walnut leaves of walnut anthracnose in Shaanxi and Sichuan Provinces. In conjunction with morphological evidence and multi-gene phylogenetic analyses of internal transcribed spacer (ITS), actin () and beta-tubulin () sequences support the introduction of three new species, namely , and . Five species of were identified to be of the species complex, of the species complex, , and of the species complex. The three new species are described and illustrated in this paper and compared with taxa in the species complex. The current results improve the understanding of species causing walnut anthracnose in China.
该物种是全球各种经济植物寄主的重要病原体。在本研究中，从陕西和四川省核桃炭疽病有症状的核桃叶片中获得了45个分离株。结合形态学证据以及对内部转录间隔区（ITS）、肌动蛋白（）和β-微管蛋白（）序列的多基因系统发育分析，支持引入三个新物种，即、和。已鉴定出该属的五个物种属于物种复合体、物种复合体、物种复合体的、和。本文描述并说明了这三个新物种，并与物种复合体中的分类群进行了比较。目前的结果增进了对中国引起核桃炭疽病的该属物种的了解。
