Abstract

(Phyllostictaceae, Botryosphaeriales) includes plant pathogens, endophytes and saprobes, occurring on various hosts worldwide. During the present study, isolates associated with leaf spots were obtained from the hosts and , and identified based on morphological features and phylogenetic inference from the analyses of five loci (ITS, LSU, , and ). Results supported the introduction of two novel species, namely and . Phylogenetically, and formed two well-separated lineages in the and species complexes, distinguishing from all presently accepted species in this genus by DNA sequence data. Morphologically, and have the typical structure of the genus , and differed from their closely related species by the length of the conidial appendage.

摘要

（叶点霉科，葡萄座腔菌目）包括植物病原菌、内生菌和腐生菌，广泛分布于世界各地的各种寄主上。在本研究中，从寄主和上获得了与叶斑相关的分离物，并根据形态特征以及对五个基因座（ITS、LSU、、和）分析的系统发育推断进行鉴定。结果支持引入两个新物种，即和。在系统发育上，和在和物种复合体中形成了两个明显分开的谱系，通过DNA序列数据与该属目前所有已接受的物种区分开来。在形态上，和具有该属的典型结构，并且通过分生孢子附属物的长度与它们的近缘物种有所不同。
