It would also be very helpful to see the underside. Pry back a lobe tip near the growing margin. If it’s paler or lacking rhizines near the margin then make sure to pry back enough to show what it looks like under more mature portions of the thallus.

Ahtiana should be yellowish

I’m not sure what I’d suggest, though. Notice the coarse soredia in the lower right corner of the photo, that will be important to get to species level. Also, there are no obvious pycnidia (small shiny black bumps), so I’d say it is in the Parmelia sensu lato. Ahtiana is in Cetraria sensu lato, which is characterized loosely by often having prominant marginal pycnidia — Platismatia, Tuckermannopsis, Vulpicida, and their kin. I’d try Hypotrachyna or Myelochroa or Canoparmelia or… I don’t know, maybe Parmelinopsis??
