Notes: this is the first orange species I’ve seen so far. I’m not sure if it’s just lacking nutrients, polluted, or just an orange species.

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).
