It was seen on a branch on the floor having fallen from the tree above, it was right near the coast.
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.
It certainly looks like a fruticose lichen to my (inexperienced) eyes but I don't think it's Sea Ivory. Sea Ivory grows on rocks on the sea shore not on trees. See this link http://www.theseashore.org.uk/theseashore/SpeciesPages/Sea%20ivory%20lic....
Evernia prunastri is the main lichen on top of the branch but there is Hypogymnia physodes to the left and a Ramalina sp. below with slightly larger lobes.
As vm53 says Ramalina siliquosa is only found on coastal rocks, where it can be very common.

The area was very damp as expected, with alot of moss and other lichen present.
