This observation refers to the Caloplaca with brownish thallus that appears at the bottom of the first photo attached.
When I saw it my prognosis was that it could be a Acarospora, though strange. But easily could indicate more 10 genera before mention Caloplaca. To clarify the doubts observed a section under the microscope. Unfortunately I have pictures, but I may add that the spores are at all similar to what I have observed in the genus Caloplaca with approximate dimensions of 12-13 × 6 μm and an isthmus of 3.5-4 μm.
In a certain sense it is close to other Caloplaca that I observed before, C. variabilis, with brownish thallus and black pruinose apothecia.
