    This looks more like Rhizocarpon lecanorinum. I would never presume its geographicum unless you keyed it out. there are aroudn 40 species of Rhizocarpon in that area! Posted 5 years ago

The Rhizocarpon geographicum

"Rhizocarpon geographicum" is a species of lichen, which grows on rocks in mountainous areas of low air pollution. Each lichen is a flat patch bordered by a black line of spores. These patches grow adjacent to each other, leading to the appearance of a map or a patchwork field.
