Small patches of small yellow-orange lobes. K+ crimson. Growing on stone in north wall of church. (Different areas more in focus in each image.) Possibly Xanthoria candelaria sens. lat.
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.
This looks like true X. candelaria to me. Many of the lobes are upright and very narrow.
Thanks for details suggesting it looks like true X. candelaria. Also thanks for extra information elsewhere on Caloplaca teicholyta and Dirina massiliensis.
