I was taking these photos as my hiking partners stood by—not too patiently :) Thanks for mentioning the importance of thallus attachment.


Not sure about Rhizoplaca

It definitely could be, but I can’t tell from the photos if it’s attached throughout below (crustose), or only near the center (umbilicate). The overall habit resembles the Lecanora muralis group, too, which would be truly crustose throughout.
