Abstract

The phytopathogenic genus, Entomosporium can cause serious leaf diseases worldwide. Entomosporium has long been regarded as a synonym of Diplocarpon. However, different morphologies between Entomosporium and Diplocarpon make this doubtful. Based on morpho-phylogenetic analyses, the placement of the genus was re-evaluated in this study. The combined the internal transcribed spacer gene region (ITS) and the 28S large subunit ribosomal RNA gene region (LSU) phylogenetic analysis shows that Entomosporium is an independent clade within Drepanopezizaceae and formed a sister clade to the generic type Diplocarpon. Moreover, Hymenula and Pseudopeziza do not cluster in Drepanopezizaceae. We propose to resurrect the name Entomosporium, and exclude Hymenula cerealis and Pseudopeziza medicaginis from Drepanopezizaceae and propose to treat them under Ploettnerulaceae. A new species, E. dichotomanthes is also introduced from China based on morpho-molecular analyses which is associated with Dichotomanthes tristaniicarpa.
