The genus includes important plant pathogens, endophytes and saprobes with a wide host range and geographic distribution. In this paper, 74 strains isolated from various substrates such as bamboo leaves, tea plants, soil and air from karst caves in China were examined using a multi-locus phylogeny based on a combined dataset of ITS rDNA, TEF1 and TUB2, in conjunction with morphological characters, host association and ecological distribution. Eight new species were described based on their distinct phylogenetic relationships and morphological characters. Our results indicated a high species diversity of with wide host ranges, amongst which, Poaceae and Cyperaceae were the major host plant families of species.
该属包括重要的植物病原体、内生菌和腐生菌,寄主范围广泛,地理分布广泛。本文基于ITS rDNA、TEF1和TUB2的联合数据集,结合形态特征、寄主关联和生态分布,利用多位点系统发育方法对从中国喀斯特洞穴的竹叶、茶树、土壤和空气中等各种基质分离出的74株菌株进行了研究。基于其独特的系统发育关系和形态特征描述了8个新物种。我们的结果表明该属具有高物种多样性,寄主范围广泛,其中禾本科和莎草科是该属物种的主要寄主植物科。
