Lecanora chlarotera, Lecanora dispersa and Lecanora muralis. January 2017. |
These are three species from the same genus. The first one, Lecanora chlarotera, grows typically on trees, in a patchwork with some soepcies from different families.
Here's a typical example.

Lecanora muralis, on the other hand, could not have a more different environment. It grows all over the pavements, often in busy areas. It prefers not to be walked on too much, but can survive a bit of footfall.

The third example, in the middle of the top picture, is Lecanora dispersa. This is either rarer or just less often recorded. It's not so easy to see, because what you do see is little more than an array of the fruits, without a visible thallus. I found that one right next to L. muralis, and I only found it when looking at my photos.
