In this study, the diversity of species in section associated with symptomatic plants in the Cyperaceae and Juncaceae families was assessed. Multilocus sequence analyses of the rDNA internal transcribed spacer (ITS) region and parts of major allergen (), glyceraldehyde-3-phosphate dehydrogenase (), second largest subunit of RNA polymerase II (), and translation elongation factor 1-alpha () genes revealed the presence of two previously known species, and , and three new species, which are described here as , sp. nov., , sp. nov., and , sp. nov. These new species were characterized morphologically with respect to the dimensions of conidia, the number of pseudosepta in mature conidia, and the type of conidium apical beak. According to the results of phylogenetic analyses, the presence of long, filiform true beak is not a reliable morphological indicator for grouping species in sections and and phylogenetic species recognition should be used. All identified species were described, illustrated, and their morphology and phylogenetic relationships with other species in section were discussed.
在这项研究中，评估了与莎草科和灯心草科有症状植物相关的 种的多样性。核糖体 DNA 内转录间隔区（ITS）区域和部分主要过敏原（）、甘油醛-3-磷酸脱氢酶（）、RNA 聚合酶 II 的第二大亚基（）和翻译延伸因子 1-α（）基因的多位点序列分析揭示了存在两个先前已知的物种， 和 ，以及三个新物种，这里描述为 、sp. nov.、 、sp. nov. 和 、sp. nov.。这些新物种在形态上通过分生孢子的大小、成熟分生孢子中的假隔数以及分生孢子顶端喙的类型来区分。根据系统发育分析的结果，长而丝状的真正喙并不是分组 和 节中物种的可靠形态指标，应该使用系统发育种识别。所有鉴定的物种都进行了描述、说明，并讨论了它们与 节中其他物种的形态和系统发育关系。
