Sure has the appearance of Lecanora with those closely-packed apothecia turning convex in age (both the bumps and the cups are apothecia, just in different stages of development). Nothing stands out in the sample of photos in Brodo’s L. of N.A., and USFS didn’t collect crusts for their database (for the most part).
