Evernia prunastri
Lichen of some sort - but I never got around ID-ing these fellows :)
Near a moor (Balata to) between trees

Oakmoss it is, I would say :)
Not that I have any idea of lichen, but the one you suggested seems more like one that creeps along things like bark.
This one was hanging kind of bushy down a branch.
