See this name description for Xanthoria.

Where does that leave observation_88828?? I’m voting for ulophyllodes…

Just added three photos

I hope I will not be disqualified and kicked out of MO for adding few photos to the same opbservation, but taken a week later. I don’t know if that kind of cheating is tolerated :-) They’re the very same cluster of lichen, and only a week apart.
On the different note, this X.weberi is on rock and has very distinct features. But it’s not like the observation 88828 at all. So what’s that one?

Yes, it looks like the illustration you mentioned

Now I know what to look for in this species. The only problem is – I didn’t know that similar stuff used to be called X.fulva. I thought X.fulva was the stuff like in those observatons you mention just below – with raised central lobes and broad lobe tips. Now I don’t know what those are. They’re pretty common, though, so I’ll obtain a specimen soon, I hope.

Aha! Now this looks like proper X. weberi at last!

Doesn’t this look just like the photo in Lindblom’s 2006 paper? Narrow ascending lobes, soredia under tips, colonial growth form, a bit too orange perhaps, but this is otherwise a perfect match. This is what I’m used to X. fulva looking like.

Now. You’ve also got some undeniable X. ulophyllodes (e.g., observation 88909, observation 88899). What about all the broad-lobed things in between with erect central lobes, pimply pycnidia and no rhizines?? (e.g., observation 88828, observation 88906)

What the heck is this?

I was actually taking photos of Candelaria concolor and some Caloplaca species when I got this one – I only realised this when I uploaded photos to my computer. I will definitely go back and retake the photos at some point.
