Options are usually: Candelariella, Acarospora, Rhizocarpon geographicum. But some species of Caloplaca can be that pale (C. citrina, for example, would be common on urban sidewalks). So, you need to see the apothecia, and K test is always a good idea until you’re familiar with the common suspects.
