What a mess

Yes, I see that now. And in the first photo, I think that’s what is in the upper left corner. I will take those 2 photos off and put them in as D. scruposus.

Hold on a second!

Am I seeing things? I see two urceolate Diploschistes-like apothecia in that fourth photo. Huh? Is it possible that’s Diploschistes scruposus??

I think it is the R. opiniconensis

I have added another photo, taken on same sandstone outcrop, of what I am almost positive is a more-developed speciman than the one in the original photos.

Something doesn’t look quite right for Protoparmeliopsis muralis

I have some photos of Rhizoplaca opiniconensis that look remarkably similar, though. (And others that look nothing like this!) It’s worth considering at least.
