represents a commercially and ecologically important tree species in China, but suffers from canker diseases in Jiangxi Province. Synnemata, pycnidia and ascomata were discovered on cankered tissues. Strains were obtained from single ascospore or conidium within the fruiting bodies and identified based on morphological comparison and the phylogenetic analyses of partial ITS, LSU, and gene sequences. As a result, two species were confirmed to represent two kinds of synnemata. One of these species is described herein as ; and is illustrated showing ascomata, pycnidia and synnemata. is distinguished from by the colour of the synnematal tips. Additionally, can be distinguished from the other gnomoniaceous genera by the formation of synnemata.
在中国是一种具有商业和生态重要性的树种，但在江西省遭受溃疡病侵害。在溃疡组织上发现了分生孢子座、分生孢子器和子囊壳。从子实体中的单个子囊孢子或分生孢子获得菌株，并根据形态比较以及部分ITS、LSU和基因序列的系统发育分析进行鉴定。结果，确认两个物种代表两种分生孢子座。本文将其中一个物种描述为 ；并展示了子囊壳、分生孢子器和分生孢子座。 通过分生孢子座顶端的颜色与 区分开来。此外， 可通过分生孢子座的形成与其他日规壳属区分开来。
