I didn’t pour water on these :-)

Mayrhofer & Sheard say this in the generic description in Sonoran Flora:

Ascomata: apothecial, initially cryptolecanorine, finally becoming lecanorine or lecideine, first innate or immersed, becoming adate or sessile.

Only other option is Lecanora (e.g., L. muralis group), but I’d stick with Dimelaena. The bumpy one must be environmental. Had a hard winter a few years ago or something.

(I admit that this is a photogenic species in the worst of times, but wow!!, these are incredible even by its high standards! Simply breathtaking.)

Dimelaena oreina?

These were mixed and very similar to what I identified as Dimelaena oreina (that’s not guaranteed either). My only problem with these was: they have raised apothecia, while D.oreina usually have sunken ones. Also, the very first photo in the lineup looks more bumpy than others – I’m not sure it’s the same species.
