Lichen

This Lichen has been sitting in a clamp on a shelf at the studio, patiently waiting to be blipped.  I picked it up on a walk down the lane after high winds months (nearly a year?) ago.  Not needing a blip of it that day I  put it in a clip on a shelf.  Today we were removing the very last items from the studio.  The lichen obviously needed to move.

I think this is Evernia prunastri, again my knowledge of Lichens is very scant.
