Dead leaves of Musa sp. (banana) were collected in northern Thailand during an investigation of saprobic fungi. Preliminary morphological observations revealed that three specimens belong to Dictyoarthrinium. Phylogenetic analyses of combined SSU, LSU, ITS and tef1-α sequence data revealed that Dictyoarthrinium forms a clade in Didymosphaeriaceae (Massarineae, Pleosporales, Dothideomycetes) sister to Spegazzinia. Based on contrasting morphological features with the extant taxa of Dictyoarthrinium, coupled with the multigene analyses, Dictyoarthrinium musae sp. nov. is introduced herein. Our study provides the first detailed molecular investigation for Dictyoarthrinium and supports its placement in Didymosphaeriaceae (Massarineae, Pleosporales, Dothideomycetes). Previously, Dictyoarthrinium was classified in Apiosporaceae (Xylariales, Sordariomycetes).

多基因的系统发育证据表明，盘藻属属于双孢丝菌科（Pleosporales，Dothideomycetes）和盘藻属。十一月 来自泰国的Musa。

芭蕉科的枯叶。（香蕉）是在泰国北部对腐生真菌进行调查时收集的。初步的形态学观察表明，三个标本属于双歧杆菌。结合SSU，LSU，ITS和tef1-α序列数据进行的系统进化分析表明，网藻菊属在Spegazzinia姐妹的Didymosphaeriaceae（Massarineae，Pleosporales，Dothideomycetes）姐妹中形成进化枝。基于与现存的盘藻类群不同的形态特征，结合多基因分析，盘藻属。十一月 这里介绍。我们的研究提供了第一个详细的双歧杆菌属分子研究，并支持其在双歧杆菌科中（马萨里科，Pleosporales，Dothideomycetes）的放置。以前，白屈菌属被归类为Apiosporaceae（Xylariales，
