The field of possible genera is simply too large. In North America, James Lendemer put together a rough key of many of the sterile crustose species, but even that is still very much a work in progress. I don’t know if there is anything similar for Europe. Unfortunately Lendemer’s key didn’t yield anything likely for yours.

Trying to classify them …

is like a long shot, despite the chemical reactions being clear.

Maybe some sort of Phlyctis? I can’t find apothecia. Are they hidden in there somewhere? I’m considering Lecidea tessellata and maybe Aspicilia, too.
