I thought about it.

I thought it might be A.cinerea, which takes all kinds of forms and patterns. I just wasn’t sure it can get this much warty – it almost looks like Pertusaria species. I used to think Aspicilia would be a bit flatter. I have several more photos of what looks like the same species that I’ll post later. Wisconsin should have 5 species of Aspicilia. “Lichens of Wisconsin” differentiates between A.cinerea and A.caesiocinerea based on number of apothecia in areoles – usually one in A.caesiocinerea and 1, 2 or more in A.cinerea. What do you think about this method? I lack any chemicals at all to test and don’t have microscope powerful enough to see spores.
