We were just discussing another specimen doing this same odd thing with tons of tiny “aborted” apothecia from Wisconsin (observation 65608). In your case I’ll bet anything it is Xanthoparmelia (despite the apparent total lack of greenish coloration typical of the genus). There are no other big broad-lobed grayish foliose lichens with pale underside growing directly on rock in the full sun out there. (Out east we have Flavoparmelia baltimorensis as well, but that’s another story. And there’s Parmelia with a black underside out west, but it also has distinctive markings on the upper surface and differently-shaped lobe-tips.)
