Abstract

is a polyphyletic and asexual morphic genus within the family Periconiaceae (Pleosporales). The genus is characterized by a pale to dark brown stipe with an apical conidial head and ellipsoidal to oblong conidia. Species of are widely distributed throughout the world in various hosts, while most species are isolated from graminaceous plants. During our investigations of microfungal in Sichuan Province, China, 26 isolates were collected from a wide variety of graminaceous plants. These isolates corresponded to 11 species based on the examination of morphology and multi-locus phylogenetic analysis (SSU, ITS, LSU, , ). This includes six new species (, , , , and ) and five new records (, , , , and ). A comprehensive description and illustrations of the new species are provided and discussed with comparable taxa. These discoveries expand our knowledge of the species diversity of taxa in graminaceous plants in China.

摘要

是围盘菌科（格孢腔菌目）内的一个多系且无性态的属。该属的特征是菌柄颜色从浅褐色到深褐色，顶端有分生孢子头，分生孢子呈椭圆形至长圆形。该属的物种广泛分布于世界各地的各种寄主上，而大多数物种是从禾本科植物中分离得到的。在中国四川省进行微真菌调查期间，从多种禾本科植物中收集了26个分离株。基于形态学检查和多位点系统发育分析（SSU、ITS、LSU、、），这些分离株对应于11个物种。其中包括6个新物种（、、、、和）和5个新记录（、、、和）。提供了新物种的全面描述和图示，并与可比分类群进行了讨论。这些发现扩展了我们对中国禾本科植物中该属分类群物种多样性的认识。
