One was: placodioid-type (overgrowing the other), K~y C- KC+r P- UV+ bright white = L. cryophila

The other was: aggregate-type, K+ distinctly yellow C- KC- UV- P+ week yellow = atranorin probably = either L. humida or L. jackii acc. to my notes.

Perhaps chem testing will show something…

with “struggle zones” like that. There are other genera. There are Lecanora that are essentially entirely leprose (see observation 103567). I’m sure there are others, too. I wonder if any of those dark bumps are actually perithecia or apothecia? Looks like just texture in the underlying rock, but maybe not…

this lichen seems like a Lepraria – basically a mass of soredia, and not much else. Interestingly, some of it is whitish, and some of it is greenish. Also, there are those dark bands – outer perimeter of separate thallii?
