Diaporthales is a fungal order comprising important plant pathogens, saprobes and endophytes on a wide range of woody hosts. It is often difficult to differentiate the pathogens in this order, since both the morphology and disease symptoms are similar among the various species. In the current study, we obtained 15 representative diaporthalean isolates from six tree hosts belonging to plant families Betulaceae, Fagaceae, Juglandaceae, Rosaceae, and Ulmaceae from Mount Dongling in China. Six species were identified residing in four families of Diaporthales (Diaporthaceae, Erythrogloeaceae, Juglanconidaceae and Melanconidaceae). Based on morphological comparison and the phylogenetic analyses of partial ITS, LSU, , , , and gene sequences, we identified five known species (, , , and ) and one novel species (). These results represent the first study of diaporthalean fungi associated with canker and dieback symptoms from Mount Dongling in Beijing, China.
座囊菌目是一类真菌，包含多种重要的植物病原体、腐生菌和内生菌，寄生于多种木本宿主上。该目下的病原体往往难以区分，因为不同物种间的形态和病症相似。在本研究中，我们从中国东灵山地区属于桦木科、壳斗科、胡桃科、蔷薇科和榆科的六种树木宿主上获得了15株具有代表性的座囊菌目分离株。鉴定出六个物种，分属于座囊菌目的四个科（座囊菌科、红胶盘菌科、胡桃座囊菌科和黑盘孢科）。基于形态比较以及对部分ITS、LSU、 、 、 和 基因序列的系统发育分析，我们鉴定出五个已知物种（ 、 、 、 和 ）和一个新物种（ ）。这些结果代表了对中国北京东灵山地区与溃疡和枯死症状相关的座囊菌目真菌的首次研究。
