Emended Neodactylariales (Dothideomycetes): Szaferohypha gen. nov. and phylogenetically related genera

Epiphytic fungi evolved several times in Dothideomycetes, particularly within the orders Asterinales, Capnodiales, Microthyriales, and Zeloasperisporiales, but also in other, less obvious lineages. In this study, a new genus and species, <i>Szaferohypha</i> and <i>S.enigmatica</i>, isolated from the sooty mould community on the leaves of <i>Symphoricarposalbus</i> in Poland, are described based on morphology and phylogenetic analysis using sequences of four DNA loci (LSU, ITS, SSU, and <i>rpb2</i>). Due to single isolation, it is unclear whether <i>Szaferohyphaenigmatica</i> represents a very rare or accidental inhabitant of sooty mould communities. <i>Szaferohypha</i> is assigned to the poorly known family Neodactylariaceae and order Neodactylariales, together with <i>Beaucarneamyces</i>, <i>Neodactylaria</i>, and <i>Pseudoarthrographis</i>. The order and family were originally circumscribed based on the features of the genus <i>Neodactylaria</i>. Therefore, they are emended by characters of <i>Beaucarneamyces</i>, <i>Pseudoarthrographis</i>, and <i>Szaferohypha</i>.
