Resumen:
© 2020 by the authors. Licensee MDPI, Basel, Switzerland. The order Sordariales includes the polyphyletic family Lasiosphaeriaceae, which comprises approximately 30 genera characterized by its paraphysate ascomata, asci with apical apparati, and mostly two-celled ascospores, which have a dark apical cell and a hyaline lower cell, frequently ornamented with mucilaginous appendages. To produce a more natural classification of this family, we carried out a phylogenetic analysis based on sequences of the internal transcribed spacer region (ITS), the nuclear rDNA large subunit (LSU), and fragments of ribosomal polymerase II subunit 2 (rpb2) and β-tubulin (tub2) genes of several isolates from soil and of reference strains of the Sordariales. As a result, Lasiosphaeriaceae s. str. has been circumscribed for the clade including the type species of the genus Lasiosphaeria and, consequently, its description emended. In addition, the new families Diplogelasinosporaceae, Naviculisporaceae, and Schizotheciaceae are introduced to accommodate those taxa located far from the Lasiosphaeriaceae s. str. Moreover, we propose the erection of the new genera Areotheca, Lundqvistomyces, Naviculispora, Pseudoechria, Pseudoschizothecium, and Rhypophila based on morphological and sequence data. New combinations for several species of the genera Cladorrhinum, Jugulospora, Podospora, Schizothecium, and Triangularia are proposed, their descriptions are emended, and dichotomous keys are provided to discriminate among their species.
