摘要
More than 100 recent collections of Valsaria sensu lato mostly from Europe were used to elucidate the species composition within the genus.Multigene phylogeny based on SSU,LSU,ITS,rpb2 and tef1 sequences revealed a monophyletic group of ten species within the Dothideomycetes,belonging to three morphologically similar genera.This group could not be accommodated in any known family and are thus classified in the new family Valsariaceae and the new order Valsariales.The genus Valsaria sensu stricto comprises V.insitiva,V.robiniae,V.rudis,V.spartii,V.lopadostomoides sp.nov.and V.neotropica sp.nov.,which are phylogenetically well-defined,but morphologically nearly indistinguishable species.The new monotypic genus Bambusaria is introduced to accommodate Valsaria bambusae.Munkovalsaria rubra and Valsaria fulvopruinata are combined in Myrmaecium,a genus traditionally treated as a synonym of Valsaria,which comprises three species,with M.rubricosum as its generic type.This work is presented as a basis for additional species to be detected in future.
