In brief: Organism+appearance

They are caused by different fungi.
Pr usually causes many small lesions over the neck and torso that are a few mm in diameter and are lighter than the surrounding skin. Ringworm is usually one red lesion that can grow to be several cm in diameter and has a red border.

In brief: Fungus vs not!

Ringworm is caused by a fungus, is contagious, and is quite easily treated with topical creams.
Pityriasis rosea is a non-infectious rash, not caused by a fungus, that does not yet have a distinct cause. Although the lesions of p. Rosea are similar to ringworm, they are more widespread, and take a lot longer to go away. They also do not spread from person to person. Light therapy can help in p.R.
