Quoting from 1st reference: “Lecanora varia is easily recognized on account of its apothecial margin with a dull zone bordering the apothecial disc surrounded by a more or less glossy outer zone.”
This is well visible in the attached photos (particularly, the last one where the apothecia are magnified). Of course to be 100% sure only going into microscopic details. A similar specimen can be seen in the 2nd reference.
