Image of Trichophyton rubrum (Castell.) Sabour. 1911

Description:

This photograph depicts the frontal view of a Petri dish within which a colony of the African form of the fungus, Trichophyton rubrum, had been cultured. Revealed is the colonial morphology, which in this case is both glaborous, i.e., flat to cottony, and raised and ruffled at its center. Its frontal coloration can range from a white to bright yellowish-beige, as it was here, and even to a red-violet coloration. From the reverse, or from the back, the colonies display a coloration that is a light yellowish to brown, or a reddish brown.
