this with my previous observation of Arthonia radiata and everything matches. The only difference is that in former observations the thallus was pruinose. Since this feature can be ephemerous or not present, Since, on the other hand, the habitat is adequate, I think I found the species for this specimen.
Microscopy added.

I have many doubts about the classification of this specimen, including:
- The unusual form and size of the apothecia;
- The form and septation of the spores (most of the spores were shriveled in the asci);
- The alga seems “greener” than the usual Trentepohlia.
