Recognized by sight: Parmelia has flatter lobes and abundant black rhizines on the underside which is typically blacker than I see in the photos here even at the edges. I think you would find that this has no rhizines underneath, making it Platismatia. Within that genus, the conspicuous reticulate ridges make it P. norvegica or P. lacunosa, but this looks more like the former.
