tinea kerion

Favus, tinea versicolor, and the various forms of ring-worm are caused by members of the fungus group.

Tinea Favosa, or favus, is a contagious and a very stubborn disease of the skin, caused by the fungus Achorion Schoenleinii.

Ovid, in his exile at Tomi, likens the "external remorse of its cares" which his heart feels to the gnawing of the tinea.

In tinea sycosis, or ringworm sycosis, the history of the case is different.
