Ascomycota ? Phylogeny ? Sexual-asexual morph ? Taxonomy}, doi = {}, url = {http://}, pmid = {}, journal = {Mycosphere}, volume = {}, number = {}, pages = {}, abstract = {Dothidotthia and Thyrostroma species are plant pathogens causing canker, dieback and leaf spots on a wide range of hosts. However, naming species is difficult, due to insufficient protologues, poor phylogenetic understanding due to lack of sequence data from type species and low-quality illustrations. Moreover, the connections between asexual and sexual morphs of these genera are unclear. In this study, fresh samples of Dothidotthia and Thyrostroma were collected from symptomatic twigs and branches in Southern European Russia. Multi-gene phylogenetic analyses based on a concatenated LSU, SSU, ITS and TEF1 sequence data were used to investigate the phylogenetic position and relationships of the asexual and sexual morphs in these genera in Dothidotthiaceae and Pleosporineae. Our multi-gene phylogenetic analyses coupled with morphological characters showed Dothidotthia and Thyrostroma can easily be distinguished from one another. The new species, Dothidotthia aceris, D. robiniae, Thyrostroma celtidis, T. lycii, T. moricola, T. robiniae, T. styphnolobii, T. tiliae, T. ulmicola and T. ulmigenum are introduced. Descriptions, notes and illustrations are provided.} }
