Beschreibung:
Whole genome sequencing is rapidly increasing phylogenetic resolution across many groups of fungi. To improve sequencing coverage in the genus Paecilomyces (Eurotiales), we report nine new Paecilomyces genomes representing five different species. Phylogenetic comparison between these genomes and those reported previously showed that Paecilomyces paravariotii is a distinct species from its close relative P. variotii. The independence of P. paravariotii is supported by analysis of overall gene identify (via BLAST), differences in secondary metabolism and an inability to form ascomata when paired with a fertile P. variotii strain of opposite mating type. Furthermore, whole genome sequencing resolves the P. formosus clade into three separate species, one of which lacked a valid name that is now provided.
