Maybe you headed down the “cetrarioid” branch in the key?

I would have. And this specimen does have a Tuckermanella-like or Kaernefeltia-like look, to be sure. But soon as you look at the Parmelia s.l. key (in the Sonoran Flora), it should dump you out immediately at Neofuscelia / Melanelia (sensu lato: vol. I came out before Melanohalea, Melanelixia and Montanelia were split off).

Got it!

Thanks Zaca, new genus for me, but I think you definitely got it right. There are apparently 2 species here, Melanohalea subolivacea and Melanohalea multispora. Will need that compound scope to check for number of spores per ascus, otherwise mostly indistinguishable in external features.
