New genera, species, combinations, and synonyms of saprobic Dothideomycetes and Sordariomycetes from subtropical Texas, USA

As a result of long-term field work in subtropical Texas, USA, three novel genera and three new species are introduced in Pezizomycotina to accommodate new or previously described taxa lacking DNA sequence data. In the Dothideomycetes, <i>Piepenbringia</i>, gen. nov. is established for <i>Taeniolella multiplex</i> (Pleosporales incertae sedis) distant from the type species <i>T. exilis</i> in Kirschsteiniotheliales. <i>Ernakulamia americana</i>, sp. nov. (Tetraplosphaeriaceae, Pleosporales), collected on dead leaves of <i>Sabal minor</i> (Arecaceae), forms a distinct monophyletic lineage distant from representative strains of <i>E. cochinensis</i>, the type species. In the Sordariomycetes, <i>Pseudotaeniolella</i>, gen. nov. is introduced for <i>Taeniolella sabalicola</i> in Distoseptisporaceae (Distoseptisporales), also distant from <i>T. exilis</i> in the Dothideomycetes. <i>Parapenzigomyces ampelinus</i>, gen. et sp. nov. collected on dead stems of hanging vines, forms a strongly supported lineage in Xylariales distant from the type species of <i>Penzigomyces, P. nodipes</i>, in Chaetosphaeriales. A new combination in <i>Parapenzigomyces</i> is proposed for <i>P. flagellatus</i> after examination of ex-type material. <i>Sporidesmina</i> is expanded to accommodate <i>Stanjehughesia floridensis</i> and a few other stanjehughesia-like fungi that cluster together in a distinct lineage incertae sedis in Xylariales. They are distant from <i>St. hormiscioides</i>, the type species in Chaetosphaeriales; therefore, five new combinations in <i>Sporidesmina</i> are proposed. <i>Acrodictys holubovae</i>, sp. nov. (Acrodictyaceae, Sordariomycetes incertae sedis), collected on dead culms of <i>Arundinaria</i> sp. (Poaceae), is phylogenetically distant from other <i>Acrodictys</i> species having clavate or pyriform conidia with 3–4 transverse septa and distinct pores. The identity of <i>Solicorynespora foveolata</i> is revised due to its similarity to several <i>Distoseptispora</i> species. The new combination <i>D. foveolata</i> is proposed, and the name <i>D. bambusae</i> is reduced to its synonym. The genus is also expanded to include previously overlooked tretic conidiogenesis. <i>Pleopunctum ellipsoideum, D. euseptata</i>, and <i>D. meilingensis</i> are newly recorded from North America. Novel phylogenetic placements are provided for <i>Sporidesmium fragilissimum</i> and <i>Tubeufia berkeleyi</i>.
