Flavoparmelia or Flavopunctelia

Based on greenish color. Any soredia or isidia? If it is perfectly uniform color it is Flavoparmelia, if it has whitish dots on surface it’s Flavopunctelia. Seems few species of either are common that far north. At least Flavoparmelia caperata is, and I suspect strongly that the range maps in Brodo’s L of NA don’t show the full range of the others.
