Ramalina sp.
Trees
My best guess is Ramalina celastri, but it is little more than a guess as I am not so adept at identifying lichens down to species.
With lichens, it is best to note the substrate the lichen was growing on, such as a tree or rock. Even better if you know what type of tree it is. That is the kind of thing you could add to the habitat section.
