You’re right, that is odd

I’ve never seen Cladonia on top of Peltigera, either. Only other thing I can think of is C. uncialis. It is certainly an unusually stressed form, whatever it is.

Maybe,

but was not able to see the central gaping hole at the nodes characteristic of that species. The association of these two lichens seemed a bit strange to me.

I seriously doubt usnic acid in this sunburnt specimen. The branches are definitely corticate, and I think there are squamules on the branches, too, indicating that it’s not a Cladina for sure. C. furcata can definitely grow in full exposure, but this represents a new extreme for me.
