color must be off

It sure looks gray in this photo, however that would only leave Myelochroa aurulenta which is C+y KC+y around soredia (otherwise C- KC-). However, if we assume the color balance was off and that it was actually yellowish green in the field, then Flavoparmelia caperata matches perfectly. (Note that it has no pseudocyphellae, so it is definitely not Parmelia.)
