So much easier to see in retrospect. :) Thanks for posting these follow-ups!

Jim crossed my suggested on the packet name Lecanora subimmergens

The question is whether L. subimmergens can be that verrucose. This other one, L. perplexa, is supposed to have a thick verrucose thallus, so maybe that’s a better option. Who knows??

L. subimmergens is described from the Adams county where the park is located.

But can Lecanora have such a warty thallus?

Gotta be Lecanora

Which reduces it to L. cenisia, L. subimmergens and L. perplexa. The apothecia are clearly starting fully submerged… suggests maybe it’s subimmergens, then?

Have no clue…
