It will add yet one more reason to visit some day! :)
It’s rather abundant on trees at this spot, and if I looked around I’m sure there are other locations in the vicinity. The thallus underside has dark areas that I couldn’t tell if it was cortex material or wood, but it seemed to be pretty much missing the lower cortex.
