Dermatophyte species identification often remains difficult because variation of isolates in the same species, overlapping characters in cultures and problems of nomenclature. DNA sequencing recently allowed the genus and species of these fungi to be reexamined. Species names were revised according to the new nomenclature convention adopted for fungi. The conclusions of this taxonomic study were approved by expert practitioners and searchers working with dermatophytes. Important points about species definition and nomenclature changes were summarized in the present communication.
