I can’t even convince myself it’s Parmeliaceae or Physciaceae. Those pustulose soralia are unlike anything we have up here on rock, except in Hypotrachyna (e.g., H. rockii) but this looks too small. Did you get a good look at the rhizines? Hypotrachyna has conspicuously forking rhizines. Color of underside might also help. Any minute cilia in the axils or around the margins? Is the upper cortex shiny anywhere?
