The close up shows that you were right from the begining. Sorry, for giving bad trails.
Thanks, Jason, for the clarification.

See how the warts appear to be stromatic aggregations of… something… perithecia? I don’t know what it is, but it looks weird for Pertusaria

Maybe you are in …

the right way. It is very difficult to understand from photos details about the texture of the warts, for instance. I understand that it has unusual “shining”, but there are species in Pertusaria with similar looking, like P. velata or P. hemisphaerica, just to mention some.

Very strange-looking. I personally suspect something more along the lines of your Glyphis cicatricosa, one of those stromatic graphoids. But without even so much as a cross-section (let alone spores!) who can say?? Very frustrating.

But it is still neat to get a quick glimpse of what the lichen flora looks like down there. Loads of foliicoles, graphids, pyrenolichens, Coccocarpia, Phyllopsora, Cryptothecia. Occasional foliose species like Leptogium, Dirinaria, Physcia, Bulbothrix and Relicina (I forgot to get a photo of it, darn it!), even a few Cladonia and Sticta.

I agree with Danny.
