Pretty sure this must be Lecanora. Large group. All have tiny nondescript simple, smooth, hyaline, elliptical spores. Need spot tests on thallus, medulla and microscopic layers of apothecium, and often need to know if there are small or large crystals in various parts of apothecium, too (using polarized light). Or you can just guess based on photo in “Lichens of North America”…
