Used references: Lichens of North America: there are a few foliose parmelioid lichens with branched isidia in your general area (e.g., Myelochroa obsessa, maybe Parmelia squarrosa) but the wrinkles and discolorations seem more like Canoparmelia to me. Just a guess. Excellent detail in the photo! But this specimen is hard to determine: a fresh young lobe tip without isidia would be a great help (to tell whether it has pseudocyphellae (cracks or holes), maculae (light spots or lines), or if it is uniformly smooth and evenly colored); also a shot of the rhizines and/or undersurface would be nice (are the rhizines branched? is it black right to the edge? are there rhizines on the margins?).

This lichen was growing on the same branch as the brown jelly shown hear:

I’ll be sure to photo the undersides in future observations.
