Are you referring to the mass

Are you referring to the mass of foliose thalli which fill the picture? Is the red apothecia of a different species, or part of the Parmelia sulcata?

Probably Parmelia saxatilis

I have added agreement to Cladonia sp., as the presumed subject of the photograph. Clearly one of the red-fruited species, but even if we had a good view of it, identifying a montane, red-fruited Cladonia from a photograph would often be unwise. As well as the lowland species, true C. coccifera, C. borealis and others would have to be given greater than usual consideration.

I agree the foliose lichen is a Parmelia, but the definition of the photograph again makes it difficult or impossible to state which. On balance I would say P. saxatilis rather than P. sulcata.
