But it will remain tentative since he didn’t find any spores. His other comments: thallus C-; no prothallus; hypothecium clear.

That was embarrassing…

I didn’t even look at the closer photos toward the bottom. You’re absolutely right, Andrew. Definitely some sort of Arthonia.

I disagree (I hope my access to MO will not be restricted for daring to do so :-)

It’s got to be Arthonia radiata or something closely related.

Buellia looks promising

Like B. punctata or B. stillingiana or kin? Very happy on this tree, that’s for sure!
