foliose lichen

I can't see any markings that could be pseudocyphellae. No white spots or lines. Could it be Physcia stellaris ?

The pseudocyphellae...

are just barely visible as a mottling on the lobes - more subtle in P. aipolia than the coarse cracks in the cortex of Parmelia spp., though more pronounced when damp.

I agree with Ian that the other blue-green foliose sp. is a Parmelia.
