Dermatophytes (from Greek " derma" "skin" (GEN "dermatos") and "phyton" "plant") are a common label for a group of fungus of "Arthrodermataceae" that commonly causes skin disease in animals and humans. Traditionally, these anamorphic (asexual or imperfect fungi) mold genera are: "Microsporum", "Epidermophyton" and "Trichophyton". There are about 40 species in these three genera. Species capable of reproducing sexually belong in the teleomorphic genus Arthroderma, of the Ascomycota (see Teleomorph, anamorph and holomorph for more information on this type of fungal life cycle). As of 2019 a total of nine genera are identified and new phylogenetic taxonomy has been proposed.
