Foliose, pale gray-green lichenized fungus with flat, black apothecia (with gray-green collars). Apothecia are disc-like structures which contain spores. Physcia species are within the family Physciaceae and are considered lichen-forming fungi. Lichens are composite organisms comprised of a fungus being inhabited by algae or cyanobacteria.

I was unable to get a species level ID as I did not do a K-test (Potassium Hydroxide) or view spores with microscopy.
