Rhizines hard to see

Every source stresses the squarrose rhizines, but your picture is typical — they all sure look simple to me! If you were to scour it very closely (esp. toward the center of the thallus) you would presumably find a few rhizines with short, fine, perpendicular side-branches. The alternative character is a couple rhizines which are forked instead. (That would indicate P. saxatilis or P. barrenoae perhaps, but neither is known from your area, I think.)

Anyway, this is certainly sorediate. P. sulcata is much more common where you are. A little farther south in the Cumberland Plateau and southern Appalachians, P. squarrosa becomes as common or even more common.
