<i>Sporocadaceae</i> revisited

Abstract

<i>Sporocadaceae</i> is a species-rich and cosmopolitan fungal family including species of plant pathogens, endophytes or saprobes, and parasites of humans and animals. The taxonomy of <i>Sporocadaceae</i> has recently been revised using a polyphasic approach. However, much remains unknown about the diversity of species and their host associations. A collection of 488 strains, mostly from China and associated with 129 host plant species, was studied based on morphological comparisons and multi-locus (LSU, ITS, <i>tef-1α</i>, <i>tub2</i>, and <i>rpb2</i>) phylogenies. Our results revealed that they belonged to 86 species, one new genus (<i>Cavernicola gen. nov</i>.) and seven known genera, including <i>Discosia</i>, <i>Monochaetia</i>, <i>Neopestalotiopsis</i>, <i>Pestalotiopsis, Seimatosporium</i>, <i>Seiridium</i> and <i>Sporocadus</i>. Of these, 43 new species and three new combinations (<i>Dis</i>. <i>kaki</i>, <i>Mon</i>. <i>bulbophylli</i>, and <i>Neo</i>. <i>keteleeriae</i>) are proposed in this paper. In addition, <i>Neo. vaccinii</i>, <i>Pes. kaki</i> and <i>Pes. nanjingensis</i> are synonymised under <i>Neo. hispanica</i>, <i>Pes. menhaiensis</i> and <i>Pes. sichuanensis</i>, respectively. We also corrected seven problematic sequences of type materials of previously published species, namely <i>Neo</i>. <i>iranensis</i> (<i>tef-1α</i>, ITS, <i>tub2</i>), <i>Pes</i>. <i>jesteri</i> (<i>tef-1α</i>), <i>Pes</i>. <i>photinicola</i> (ITS, <i>tub2</i>) and <i>Pes</i>. <i>yunnanensis</i> (ITS). Based on this study, <i>Pestalotiopsis</i> and <i>Neopestalotiopsis</i> are the most commonly detected genera within the <i>Sporocadaceae</i> family, associated with 84 and 70 plant species, respectively. Furthermore, considering the importance of <i>Sporocadaceae</i> and the fact that commonly used loci provide little valid information for species delimitation in this family, especially for <i>Neopestalotiopsis</i> and <i>Pestalotiopsis</i>, we initiated a phylogenomic project in this study. It will not only contribute to the knowledge of species boundaries but will also provide an important basis for evolutionary studies and research on secondary metabolites in <i>Sporocadaceae</i>. <b>Taxonomic novelties: New genus:</b> <i>Cavernicola</i> P.
