Plants play an important role in maintaining the ecological balance of the biosphere, but often suffer from pathogenic fungi during growth. During our continuing mycological surveys of plant pathogens from terrestrial plants in Jiangxi and Yunnan provinces, China, 24 strains of isolated from diseased and healthy tissues of plant leaves represented eight new species, viz. , , , , , , and . Multi-locus (ITS, and ) phylogenetic analyses were performed using maximum-likelihood and Bayesian inference to reveal their taxonomic placement within . Both molecular phylogenetic analyses and morphological comparisons supported them as eight independent taxa within . Illustrations and descriptions of these eight taxa were provided, in conjunction with comparisons with closely related taxa in the genus. This work highlights the large potential for new fungal species associated with diseased plant leaves.
植物在维持生物圈的生态平衡中发挥着重要作用，但在生长过程中常遭受病原真菌侵害。在中国江西省和云南省对陆生植物病原真菌进行的持续真菌学调查中，从植物叶片的患病和健康组织中分离出24株菌株，代表了8个新物种，即[此处原文缺失8个新物种的具体名称]。使用最大似然法和贝叶斯推断进行多位点（ITS、[此处原文缺失另外两个基因名称]和[此处原文缺失另外两个基因名称]）系统发育分析，以揭示它们在[此处原文缺失某个分类单元名称]中的分类地位。分子系统发育分析和形态学比较均支持它们为[此处原文缺失某个分类单元名称]内的8个独立分类群。提供了这8个分类群的图示和描述，并与该属的近缘分类群进行了比较。这项工作突出了与患病植物叶片相关的新真菌物种的巨大潜力。
