    Thanks to next-generation sequencing (NGS) technologies, the diversity of fungi can now be investigated through the analysis of their genome sequences. Naviculisporaceae is a family within the Sordariales, whose diversity is not well-known, with only one genome sequence published for this family. Here, we report on the isolation and cultivation of 20 new strains of Naviculisporaceae. Their genome sequences, as well as those of the five commercially available strains, were determined, thus providing complete genome sequences for 25 new Naviculisporaceae strains. Species delimitation was conducted using a combination of (1) ITS + LSU phylogenetic analysis of the new isolates along with other known species of the family, (2) comparisons between DNA barcode sequences of the new strains with those of the known species, and (3) average genome-wide nucleotide identity calculation. We built a phylogenomic tree and studied the organization of the mating-type locus. In vitro fruiting was obtained for 16 strains, enabling the definition of seven new species, namely Pseudorhypophila gallica, Pseudorhypophila guyanensis Rhypophila alpibus, Rhypophila brasiliensis, Rhypophila camarguensis, Rhypophila reunionensis and Rhypophila thailandica, as well as two new combinations, namely Pseudorhypophila latipes and Pseudorhypophila oryzae. Eight strains for which in vitro fruiting was not obtained may belong to additional new species. These results expand the known diversity of the Naviculisporaceae and greatly enlarge the genomic data available for the family.

    Podospora anserina (Rabenh.) Niessl is a model fungus that was shown to belong to a complex of seven species with morphologically indistinguishable sexual fruiting bodies. Through the morphological analyses and ITS (Intergenic Transcribed Spacer) sequences of 86 newly-isolated strains, as well as the genome sequences of five strains, we show that members of the P. anserina species complex present different distribution ranges in metropolitan and overseas France. Podospora anserina is present all-over metropolitan France, including Corsica, while P. comata Milovtz. is restricted to the Northern part and P. pauciseta (Ces.) Traverso to the Southern part of continental France. The Guadeloupe hosts P. pseudoanserina C.Boucher, T.S.Nguyen & P.Silar and La Réunion island a species new to science, described here as Podospora reunionensis Silar, sp. nov. This species is closely related to P. comata, but exhibit clear morphological and biological differences.
