Having just gone through a few hundred observations on MO, I’m pretty skeptical of color of photos right now! :) Heaven only knows what this thing is. And maybe Jim Bennett if he has the specimen.

Tiny lobules

The entire outer edge of lobes is covered by tiny lobules that look like soredia from afar. If it’s C.robbinsii, is it reasonable for it to have different colors? (compare to Observation 156893)

I doubt C. apodocarpa

C. apodocarpa should have more tongue-like primary squamules, this has some sort of lobulation or even soredia(?) on the margins. Also, I note that it looks significantly greener than the other Cladonia in the last photo. It makes me wonder if it has usnic acid (which your spot tests might support). The lack of podetia may not necessarily rule out C. carneola. Otherwise usnic acid would indicate C. robbinsii, I think that’s the only truly apodetiate species with usnic acid.

To be identified.

I encounter lots of similar lichen around here – with secondary lobules all over. One of my finds (not posted on MO) was identified as C.apodocarpa and looked very similar, although I’m not convinced at this point. My preliminary testing seemed to show faint K+ yellowish, which persisted through KC+.
