Subtly different

The lobe shape is broader and more rounded, more overlapping, and the surface is faintly reticulate, and the soralia don’t look pustulate. The top photo looks most like Canoparmelia texana. Maybe the bottom one, too. Another to consider is C. cryptochlorophaea. K, C and KC tests on the medulla will distinguish them.

The second photo has isidia, probably making it C. caroliniana. Although strictly, you need to rule out C. amabilis and the brand-new C. eganii: check if lower surface is white to at most tan – C. amabilis – and do K test on upper surface – C. eganii is the only one with K- cortex.
