I don’t think that genus ever occurs on bark, and it has small black lecideine apothecia. Maybe you meant Rhizoplaca? Still, this is clearly crustose, and again, on bark not rock. I think your only choices are Lecanora or Ochrolechia. Ochrolechia requires careful K, C and UV test on cortex and medulla and disk of apothecia. Most species have some C+ red or pink somewhere, which is pretty rare in Lecanora. Spore size and overall size and “luxuriousness” and color of the apothecia together all help confirm the genus.
