          Abstract

          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 ).
