Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
My understanding is that R. siliquosa is more likely found on rocks etc close to the coast, near the high water mark, and it would be unusual on a tree well inland. The branched appearance and soredia pattern makes me think this may be Evernia prunastri.
Thanks, ajm. Makes sense!
