Trichophyton is a genus of fungi, which includes the parasitic varieties that cause tinea, including athlete’s foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia.
