This looks most like a sick Heterodermia, maybe H. speciosa. Orange pigment in truly orange species is from anthraquinones (usually) which react very strongly K+ wine/red. This looks too brown. And the overall shape just has the look of Heterodermia, not Xanthoria sensu lato (which would be the prime suspect for truly orange foliose lichens).
