Homortomyces is introduced as a new coelomycetous genus associated with leaf spots onCombretum erythrophyllum trees growing near and around the Sterkfontein caves, Maropeng, South Africa. Based on its transversely septate, brown conidia, the presence of paraphyses, and percurrent proliferation of the conidiogenous cells, the genus resembles Stilbospora (Melanoconidaceae, Diaporthales). It is di...
We here taxonomically revise the suborder Massarineae (Pleosporales, Dothideomycetes, Ascomycota). Sequences of SSU and LSU nrDNA and the translation elongation factor 1-alpha gene (tef1) are newly obtained from 106 Massarineae taxa that are phylogenetically analysed along with published sequences of 131 taxa in this suborder retrieved from GenBank. We recognise 12 families and five unknown lin...
PREMISE Fossils can reveal long-vanished characters that inform inferences about the timing and patterns of diversification living fungi. Through analyzing well-preserved fossil scutella, shield-like covers fungal sporocarps, we describe a new taxon early Dothideomycetes with combination unknown among extant taxa. METHODS Macerated clays from Potomac Group, lower Zone 1, Lower Cretaceous (Aptia...
Many necrotrophic plant pathogenic fungi belonging to the class of Dothideomycetes produce phytotoxic metabolites and peptides that are usually required for pathogenicity. Phytotoxins that affect a broad range of plant species are known as non-host-specific toxins (non-HSTs), whereas HSTs affect only a particular plant species or more often genotypes of that species. For pathogens producing HST...
A culture-based survey of staining fungi on oil-treated timber after outdoor exposure in Australia and the Netherlands uncovered new taxa in Pezizomycotina. Their taxonomic novelty was confirmed by phylogenetic analyses of multi-locus sequences (ITS, nrSSU, nrLSU, mitSSU, RPB1, RPB2, and EF-1α) using multiple reference data sets. These previously unknown taxa are recognised as part of a new ord...
The ascomycetous genus Scirrhia is presently treated as a member of Dothideomycetidae, though uncertainty remains as to which family it belongs in Capnodiales, Ascomycota. Recent collections on stems of a fern, Pteridium aquilinum (Dennstaedtiaceae) in Brazil, led to the discovery of a new species of Scirrhia, described here as S.brasiliensis. Based on DNA sequence data of the nuclear ribosomal...
