Jim Bennett agrees it’s O.viridis too :)

He says the were only one or two observations in the state before – perhaps the species is under-collected.

I am not sure of the species – probably O.varia?

The growth pattern is different from what I observed before. These guys form small (not bigger than half inch) circles, and apothecia is much smaller than what I am used to seeing in O.varia. Basically you only see tiny dots with naked eye. But Door County produces lots of weirdly looking lichen, that turn out to be just a variations of common species. It also has lots of rare species recorded there. What about Graphis?
