Re : Blue stone lichen id ?
Here I (only) suspect that this could be a Caloplaca, like C. albopruinosa, which has an endolithic thallus and blue pruinose apothecia with white margins; There are some other Caloplaca with somewhat similar apothecia, but the thallus is not endolithic, like C. chalybaea and C. variabilis.
Hope this can help,
