Foliose lichen

Foliose lichen

Observation - Foliose lichen. Description: A foliose lichen on the wooden deck of a jetty on a freshwater loch. Reminiscent of Palmeria sulcata ... but is it too flat and lacking the networks of white pseudocyphellae on the surface? Edit: 2nd photo added (I think of the same species.)
