Evernia prunastri?

Observation - Evernia prunastri?. Description: Fungi and lichens are not an area I am familiar with. This took my attention because the 'leaves' were so big compared with lichens I have seen at other times. I looked in my guide books and the closest I can match it to is the one named. Is this correct?
