As I mentioned in other observations some coincidences may happen when looking for lichens. This particular species, the unique of the genus Pyxine I encountered up to now, I saw before half a dozens of times, say. This particular day I observed it twice in two different places, separated by more than 1 Km. At the 2nd place I also observed (what I believe to be) another species of Pyxine.
A special reference to the underside: mostly black and near the margin becomes whitish and some bluish tons, surrounding the margin. This is mentioned to happen in this genus, according to the reference .
Also to mention that both this specimen and the one in observation 97305 have plently of brown dots on the thallus: I don’t know if these are pycnidia (according to the reference the pycnidia in this species is immersed) or some parasite.
