This place should be called “The lair of Ochrolechia” such is the profusion of specimens that are developing here. It is a depression of small hills that converge there. The other lichens living here are mainly Aspicilia and Cladonia. A small sample can be seen in the photograph labeled as “Habitat”, where some of the specimens photographed are marked.

Amazing effect. But surprisingly it’s not uncommon with lichens. Things that are generally rare, are suddenly abundant in one very localized area. I wonder if it is the same with plants, mushrooms, etc., too? It might have something to do with lichens requiring ideal environment for both alga and fungus simultaneously: presumably a rarer circumstance than optimizing for a single organism, and maybe all the more spectaular when it happens.
But is is incredible as there are places where it seems that all the necessary conditions for development of certain species are fulfilled. This is one of the species that I observed several times in different places, but most of the times only one or two specimens. Here is impossible to say how many they are and at some stones is almost a continuum.
