                               Little Brown Dots - Lichen? Fungus?
Description:

Not in a park or a garden but on a wooden post beside a road.
Each dot is so tiny, I only discovered these were there when I enlarged a photo. Went back to take this.
The area covered in the full sized picture is . . . a centimeter from top to bottom? Each dot is brown and domed and sitting in a white ring. I'm guessing this is the fruiting body of a lichen. ? ? ?
Also wondered about Common Grey Disco (Mollisia cinerea) - except it isn't grey, it's definitely brown.

Lecanora

Yes, it is a lichen, a species of Lecanora - characterised by the "jam tart" fruiting bodies (apothecia). Lecanora is a large genus with many species macroscopically very similar. It is most likely L. saligna or L. pulicaris - which really need to be confirmed by chemical and microscopic characters.

Lichen

Thanks, Lecanora, for your ID and comment. I find lichen hard to identify, hard to understand - yet am dazzled by it!
