Haha! If you’ve mastered hypogeous fungi, lichens should be a cinch. :) Happy to help.

Thanks, Jason!

Found it immediately, as I suspect you knew I would. The yellow coloration is striking, which may be why Brodo calls it Flame lichen, and certainly the scientific name is a clue, too. There’s a much wider world out there today! Lichens are totally cool! But my expertise is still in the (young) learner stage, I’m afraid.

Surely it must be Candelaria?

But I guess some Xanthoria s.l. can also rarely be that pale and that small. Nothing else has a chance.
