All spot tests negative: K- C- KC- P- UV-. Hard to see in photos, but this has a green cortex with round to slightly irregular yellowish/greenish soralia which remain distinct even in old parts of the thallus. A few tiny black discose apothecia were present: spores hyaline, 1-septate, ~17×8µm; hymenium brownish, epihymenium and exciple dark brown.

I think this is similar to an observation 88193

It seems pretty common on trees around here. I’m itching to know what it is. I believe J.Bennett has the sample of this – let’s wait for his verdict too.
