They may sometimes appear more red on the outside, where the ring is, and scaly and white in the inside of the ring. But just to be completely sure, you might just want to go to the doctor to get a diagnosis. When doctors diagnose a patient for a ringworm, they usually get a skin biopsy, which is taking a sample of the skin and getting it tested in a lab to see if there is any presence of fungus found, or they use a black light which makes the fungus glow if any is present, same as what scientists are now using for the testing of bats with a disease called White nose Syndrome (http://www.sciencedaily.com/releases/2014/05/140529182745.htm). Before the scientists thought of even using this procedure of testing for bats, the bats had to be killed to check for the disease, until one day a scientist (still unknown to this day) realized that in caves the wings of bats glow in dark areas. Thus putting the idea together that the black light testing on humans used for ringworms can also be used for bats as well. For the procedure, “UV light is directed at the wings of bats with white-nose syndrome”, and then the areas infected with fungus, “produce a distinctive orange-yellow
