It’s those deeply-divided squamules

I think if you did a K test you’d find it is intense yellow from thamnolic acid (although the K- variety does also occur in the area). I know it looks weird for C. didyma, which is supposed to be a sorediate species, but I’ve seen this form a number of times in the Smokies, especially in shaded wet places.
