it does occur in Central and Eastern Europe, mainly in regions like Belarus, Karelia and Russia. I live at the Eastern margin of Central Europe, so it is possible. Would need to look for a checklist of Austria. I am pretty sure I have read there is one.

It looks like this has a continuous maybe even corticate thallus. Maybe Phlyctis argena? Does Lecanora thysanophora occur in Europe? Probably several other candidates, too. Chemistry will help confirm, but still need to find a comprehensive treatment of sterile crusts for your region to even know which species to consider. Without sexual characters, it’s hard to know where to start. You just kind of have to know from experience.
