No identification made yet.
No interactions present.
As I have replied to another of your posts, I am afraid that closer, high resolution photographs are need for lichen identification (assuming even then that the species is one that can be identified from photographs).
Here, the yellow foliose colonies are a Xanthoria, most likely X. parietina, and the diffuse yellow patches are a Caloplaca (or maybe a Candelariella), but the key details are simply not visible.
