Twenty-nine strains were morphologically similar to <em>Lo</em>. <em>bipolare</em>. A total of 174 sequences were generated from the <em>Lo</em>. <em>bipolare</em> complex. Phylogenetic analyses based on <em>TUB</em> sequence revealed 11 distinct species within the <em>Lo. bipolare</em> complex. Morphological features of the ascospores and the anatomical structure of the ascomata from both field collections as well as axenic culture, which have been reported previously as variable features at intraspecific levels, were compared to evaluate the taxonomic reliability of these features. To clarify the generic position of the 11 species, phylogenetic analyses were done on SSU-ITS-LSU-<em>tef1</em>-<em>rpb2</em> gene sequences. The <em>Lo</em>. <em>bipolare</em> complex shared phylogenetic relationships with <em>Pseudolophiostoma</em> and <em>Vaginatispora</em>, and formed an additional five distinct clades from other members of <em>Lophiostomataceae</em>. According to its phylogenetic position, <em>Lo. bipolare sensu stricto</em> was distantly related to <em>Lophiostoma</em> s. str., and formed an independent clade within <em>Lophiostomataceae. Lophiostoma bipolare</em> s. str. could be distinguished from the other lophiostomataceous genera by the clypeus around the ostiolar neck and by the thin and uniformly thick peridium. A novel genus described as <em>Lentistoma</em> was established to accommodate this species, and the epitypification of <em>Lentistoma bipolare</em> (basionym: <em>Massarina bipolaris</em>) was proposed. Other lineages of the <em>Lo. bipolare</em> complex could not be separated on the basis of the ascospore size and sheath variations, but were distinguished based on ascomatal features, such as the existence of the clypeus, brown hyphae surrounding the peridium, and the contexture of the peridium, which were stable indicators of generic boundaries in <em>Lophiostomataceae</em>. Four additional new genera with five new species were recognised based on these morphological differences: <em>Crassiclypeus</em> (<em>C</em>. <em>aquaticus</em>), <em>Flabellascoma</em> (<em>F</em>. <em>cycadicola</em> and <em>F</em>. <em>minimum</em>), <em>Leptoparies</em> (<em>Lep</em>. <em>palmarum</em>), and <em>Pseudopaucispora</em> (<em>Pseudop</em>. <em>brunneospora</em>). Three new species were added to <em>Pseudolophiostoma</em> (<em>Pseudol</em>. <em>cornisporum</em>, <em>Pseudol</em>. <em>obtusisporum</em>, and <em>Pseudol</em>. <em>tropicum</em>) and two new species were added to <em>Vaginatispora</em> (<em>V</em>. <em>amygdali</em> and <em>V</em>. <em>scabrispora</em>).

Molecular species definitions do not always coincide with existing concepts which are guided by ecological and clinical principles. In this article, we aim to bring phylogenetic and ecological data together in an attempt to develop new species concepts for anthropophilic dermatophytes. Focus is on the <em>T. rubrum</em> complex with analysis of rDNA ITS supplemented with LSU, <em>TUB2, TEF3</em> and ribosomal protein L10 gene sequences. In order to explore genomic differences between <em>T. rubrum</em> and <em>T. violaceum</em>, one representative for both species was whole genome sequenced. Draft sequences were compared with currently available dermatophyte genomes. Potential virulence factors of adhesins and secreted proteases were predicted and compared phylogenetically. General phylogeny showed clear gaps between geophilic species of <em>Arthroderma</em>, but multilocus distances between species were often very small in the derived anthropophilic and zoophilic genus <em>Trichophyton</em>. Significant genome conservation between <em>T. rubrum</em> and <em>T. violaceum</em> was observed, with a high similarity at the nucleic acid level of 99.38 % identity. <em>Trichophyton violaceum</em> contains more paralogs than <em>T. rubrum</em>. About 30 adhesion genes were predicted among dermatophytes. Seventeen adhesins were common between <em>T. rubrum</em> and <em>T. violaceum</em>, while four were specific for the former and eight for the latter. Phylogenetic analysis of secreted proteases reveals considerable expansion and conservation among the analyzed species.
