This photograph featured a Petri dish, which had been used to culture a colony of dermatophytic fungus, Microsporum ferrugineum.Dermatophytes are types of fungi that cause common skin, hair and nail infections. Infections caused by these fungi are also known by the names tinea and ringworm. It is important to emphasize that ringworm is not caused by a worm, but rather by a type of fungus called a dermatophyte. One example of a very common dermatophyte infection is athlete’s foot, which is also called tinea pedis. Another common dermatophyte infection affecting the groin area is jock itch, also known as tinea cruris.Created: 1974

Viewed from the back, i.e., reverse, this image depicted a Petri dish containing Sabouraud's (SAB) dextrose agar, upon which a Microsporum persicolor fungal colony had been cultured. As seen in this reverse view, the colonial coloration can be yellow, or may even be a red-brown. From the front, as depicted in PHIL 10904 and 10906, the colonies can be white, or depending upon the Microsporum sp., may run the gamut, sporting a yellow, beige or cinnamon color, and display a flat, or glabrous, woolly or powdery texture.Created: 1973

This Sabouraud’s dextrose agar plate culture is growing T. terrestre fungus, rose-pigmented strain x231.Created: 1963

This photomicrograph shows the asci and ascospores of the fungus Arthroderma grubyi, formerly Nannizzia grubyia.Created: 1961

Photographed from the front, this image depicted a Petri dish containing cereal agar, upon which a Microsporum persicolor fungal colony had been cultured. As was the case here, the colonies can be white, or depending upon the Microsporum sp., may run the gamut, sporting a yellow, beige or cinnamon color, and display a flat, or glabrous, woolly or powdery texture. Taxonomically, M. persicolor is a member of the phylum Ascomycota. See PHIL 10905 for a reverse view of this colony, i.e., viewed from behind.Created: 1973
