Phylogenetic revision of <i>Camarosporium</i> (<i>Pleosporineae</i>, <i>Dothideomycetes</i>) and allied genera
Аннотация
A concatenated dataset of LSU, SSU, ITS and tef1 DNA sequence data was analysed to investigate the taxonomic position and phylogenetic relationships of the genus Camarosporium in Pleosporineae ( Dothideomycetes ). Newly generated sequences from camarosporium-like taxa collected from Europe (Italy) and Russia form a well-supported monophyletic clade within Pleosporineae . A new genus Camarosporidiella and a new family Camarosporidiellaceae are established to accommodate these taxa. Four new species, Neocamarosporium korfii , N . lamiacearum , N . salicorniicola and N . salsolae , constitute a strongly supported clade with several known taxa for which the new family, Neocamarosporiaceae , is introduced. The genus Staurosphaeria based on S. lycii is resurrected and epitypified, and shown to accommodate the recently introduced genus Hazslinszkyomyces in Coniothyriaceae with significant statistical support. Camarosporium quaternatum , the type species of Camarosporium and Camarosporomyces flavigena cluster together in a monophyletic clade with significant statistical support and sister to the Leptosphaeriaceae . To better resolve interfamilial/intergeneric level relationships and improve taxonomic understanding within Pleosporineae , we validate Camarosporiaceae to accommodate Camarosporium and Camarosporomyces . The latter taxa along with other species are described in this study.
