| Four morphologically similar specimens of an unidentified perithecial ascomycete were collected on decaying wood submerged in fresh water. Phylogenetic analysis of DNA sequences from protein-coding and ribosomal nuclear loci supports the placement of the unidentified fungus together with Achroceratosphaeria in a strongly supported monophyletic clade. The four collections are described as two new species of the new genus Pisorisporium characterised by non-stromatic, black, immersed to superficial perithecial ascomata, persistent paraphyses, unitunicate, persistent asci with an amyloid apical annulus and hyaline, fusiform, cymbiform to cylindrical, transversely multiseptate ascospores with conspicuous guttules. The asexual morph is unknown and no conidia... |

| Phylogenetic analyses of DNA sequences from nuclear ribosomal and protein-coding loci support the placement of several perithecial ascomycetes and dematiaceous hyphomycetes from freshwater and terrestrial environments in two monophyletic clades closely related to the Savoryellales. One clade formed by five species of Conioscypha and a second clade containing several genera of uncertain taxonomic status centred on Pleurothecium, represent two distinct taxonomic groups at the ordinal systematic rank. They are proposed as new orders, the Conioscyphales and Pleurotheciales. Several taxonomic novelties are introduced in the Pleurotheciales, i.e. two new genera (Adelosphaeria and Melanotrigonum), three novel species (A. catenata, M. ovale, Phaeoisaria... |
