in my answer, but this one escaped me. The place is abundant in Usnea spp., but restricted to few species that I posted, and no member of U. stigosa saw there. I got the impression, as wrote in the Notes, that this was a regenerating of a broken thallus and with those red branches could only be U. rubicunda.

The overall habit looks more like Usnea strigosa group

Notice how much more densely fibrillose this is than your other (more typical-looking) U. rubicunda. I wonder if this is a fertile species that just hasn’t produced any apothecia yet. Did you actually see any isidia on it? There are several fertile species with reddish cortex like these, I believe.
