The systematics of ascomycete genera Apiorhynchostoma, Endoxyla and Pseudovalsaria are re-evaluated based on the comparison of cultural characteristics, teleomorph morphology and DNA sequence data. Analyses of internal transcribed spacer (ITS) of the ribosomal DNA operon and large subunit (LSU) of the nuclear ribosomal DNA gene sequences resolve Boliniales as a robustly supported lineage comprising Apiorhynchostoma, Camarops, Camaropella, Cornipulvina, Endoxyla and Pseudovalsaria. Within Boliniales, species of Endoxyla form a strongly supported lineage. Apiorhynchostoma curreyi and Pseudovalsaria ferruginea group with Cornipulvina ellipsoides. Species of Camarops are paraphyletic and comprise two clades, one of which includes Camaropella. Boliniaceae is emended, Endoxyla mallochii is described as new and Apiorhynchostoma trabicola is considered a synonym of Apiorhynchostoma altipetum. We also propose the combinations Endoxyla occulta, Endoxylina luteobasis and Jobellisia peckii. Keys to genera included in the Boliniaceae and to species of Apiocamarops, Apiorhynchostoma and Endoxyla are provided.

    ABSTRACT: 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.

    ABSTRACT: Sordariomycetesis one of the largest classes of Ascomycota and is characterised by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, and fungicolous, lichenized or lichenicolous taxa. The class includes freshwater, marine and terrestrial taxa and has a worldwide distribution. This paper provides an updated outline of theSordariomycetesand a backbone tree incorporating asexual and sexual genera in the class. Based on phylogeny and morphology we introduced three subclasses; Diaporthomycetidae, Lulworthiomycetidaeand Meliolomycetidaeand five orders;Amplistromatales, Annulatascales, Falcocladiales, Jobellisiales and Togniniales. The outline is based on literature to the end of 2014 and the backbone tree published in this paper. Notes for 397 taxa with information, such as new family and genera novelties, novel molecular data published since the Outline of Ascomycota 2009, and new links between sexual and asexual genera and thus synonymies, are provided. The Sordariomycetes now comprises six subclasses, 28 orders, 90 families and 1344 genera. In addition a list of 829 genera with uncertain placement in Sordariomycetesis also provided.
