Grey crustose lichen with black spots in centre (furiting bodies?) + green foliose lichen on sycamore branch
No identification made yet.
No interactions present.
There seem to be 4 lichens lurking here - 2 crustose and 2 foliose. I can only think that the main foliose lichen is Xanthoria parietina clothed in green due to dampness (?) or algae. I'm not sure about the others.
The grey crustose lichen with the black apothecium could be Lecidella elaeochroma.
