Lichen ID

Thanks for the ID. As a beginner I find it very confusing.

It is

Don't worry - I still find it very confusing! The distinguishing feature here is the network of white lines (pseudocyphellae) from which clusters of powdery propagules (soredia) develop. Parmelia saxatilis is similar, but instead produces column-like outgrowths (isidia).

Cetraria chlorophylla (now known as Tuckermannopsis chlorophylla) doesn't have these raised lines, and develops soralia (the soredia-producing structures) on the lobe margins.
