Recognized by sight: Definitely in the R. geographicum group with the pale yellow areoles and inset black lecideine apothecia. R. lecanorinum differs from the typical stuff by having “crescent-shaped areoles”. The one in the first photo could be it. (Also, R. lecanorinum has greenish epihymenium instead of reddish, but the spores are nearly the same.)

I thought it may be in this group, the typical variety was extremely common where this was found. Thanks again.
