Dermatophytes Trichophyton
Rippon (1988) accepted 22 species and four varieties in the genus Trichophyton based on morphology. DNA sequences now play a prominent role in delineating phylogenetic relationships, and as such species concepts in Trichophyton have changed. Sixteen species are now recognised in the genus. The descriptions and species concepts provided in this publication are based upon a combination of traditional morphological criteria and the current (2016) recognised phylogenetic species (de Hoog et al. 2017).
