This is a photograph of a hair plate culture of the fungus Histoplasma capsulatum.Created: 1963

This photograph depicts the reverse view of a Petri dish within which fungal colonies of Trichophyton rubrum var. granulare had been cultured. From the front, (see PHIL 10540) the colonial morphology, which in the case of T. rubrum is said to be waxy, glaborous, i.e., flat to cottony, and display from a frontal perspective, a white to bright yellowish-beige, and even a red-violet coloration. From this reverse view, the colonies display a coloration that is a light yellowish to brown, or a reddish brown.Created: 1972

This was a plate culture of the fungus Chrysosporium keratinophilum.Created: 1963

This photograph depicts the frontal view of a Petri dish within which fungal colonies of Trichophyton rubrum var. granulare had been cultured. Revealed is the colonial morphology, which in the case of T. rubrum is said to be waxy, glaborous, i.e., flat to cottony, and display from a frontal perspective, a white to bright yellowish-beige, and even a red-violet coloration. From the reverse (see PHIL 10541) or from the back, the colonies display a coloration that is a light yellowish to brown, or a reddish brown.Created: 1972

This photomicrograph revealed some of the morphology exhibited by a Trichophyton tonsurans fungal colony. Note the glaborous, or smooth velvety appearance of this colony, and early changes at its center, which in time will lead to its characteristically raised appearance, as well as its yellowish-beige colorationT. tonsurans and T. rubrum are two common dermatophytes. These two species are usually transmitted from person to person. Another common dermatophyte is Microsporum canis, which is transmitted from animals, including cats and dogs, to people. Dermatophytes like to live on moist areas of the skin, such as places where there are skin folds. They can also contaminate items in the environment, such as clothing, towels and bedding.Created: 1974
