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,

Re : Blue stone lichen id ?
Thanks. Seems right. Depending on angle of lightting the apothecia color can seem to be black instead of blue. Sample: http://dbiodbs.univ.trieste.it/italic/italic42?specie=275&us=admin
