|Description:||This photograph depicts the frontal view of a Petri dish within which a fungal colony of a Mexican isolate of Trichophyton rubrum var. rodainii had been cultured atop a medium of Sabouraud’s agar.|
Note the colonial morphology, which in this case was wrinkled with furrows and folds, as well as raised, and covered by a velvety-textured surface. T. rubrum colonies can also exhibit a glabrous, or smooth surface. On its frontal surface, as was in this case, the color can range from white to yellowish-beige, to red violet. Note PHIL 11087 for the reverse appearance of this colony, and yellowish brown to reddish-brown color range.
