This species bewilders me. I just dump everything that doesn’t belong to the groups I know into this species! :) This is from the Sonoran Flora:


The key features seem to be: blue-green algae, elongate lobes (longer than wide, versus squamules), margins lobulate but often appearing to be sorediate (to me), lower surface with ±pale tomentum (no rhizines, no black felty underlay spreading beyond the margins of the thallus), almost always growing on moss.

Seems like a possibility, I do wish there were more big pictures of it online though, I’m mostly seeing tiny Sharnoff pics which aren’t very useful for me. :/

I’ll see if I can find it again and add some more pics, I would like to see what the rhizines look like and take a closer look for apothecia now that I know what they look like. Anything else I could check for?

I’m ruling out Pannaria because it’s too dark brown. I’m ruling out Fuscopannaria because it’s clearly foliose, not squamulose. Parmeliella is also very small and squamulose. Protopannaria pezizoides is abundantly fertile. I think that exhausts the options.
