I can’t even guess. It has those really dark apothecia again. Maybe it’s a weird form of the same thing in the other two observations?

Any guess on species?

What would the (range of possible) species be here? I know, I know – it’s all guesses, but would be nice to have some tentative name. I’ll need to pick another thousand or so Lecanora specimen before I have slightest idea.

How have I never seen it before?? Yes, always worth considering parasites when you see bizarrely formed thalli.

Might an alternative (which I don’t particularly favor) be a parasitic fungus. Looking at some of the bi-colored disks at full size gives me that impression. However, looking through images of lichenicolous fungi I don’t find any that look like this.

(Possibly of interest, in the process encountered this site – http://www.lichenicolous.net/

I think the pale-colored apothecia are aborted or old. Pruinose apothecia look more “dusty” than anything else. I think this specimen is just struggling to survive. Or maybe some snail is snacking on apothecia from time to time.

Two colors

Apothecia offers two different colors – I guess some of them are pruinose and some not.
