The other (observation 82417) does look more suggestive, I agree. I’m sure I’d agree with you if I were there in person!

Those are more prominent and juicy, icluding fresh L. thysanophora on top of older ones or “ghost circles” like you can see here.

I’m still unwilling to even hazard the broadest of guesses! :)

Like observation #81373

I’m more certain now it’s a leftover from Lecanora thysanophora – see observation #81373 for better, fresher has-been specimen.

I have a feeling that this might not be a lichen, but the spots were lichens used to be after latter died. I’d like to see more photos of used-to-bes, because I don’t really know how it’s supposed to look like. I have some photos of what I think might be dead lichen on rocks, but I’m not sure.

I’ll se what I can do.

Whatever it is, I hope to avoid the ire of PETL :-)

Not much to go on, is there?

Too bad, even using the camera as a “microscope” doesn’t show any usable features! If it’s common enough in one place, you know, you can wander off trail just a bit, or look for it on the far side of trees — anywhere you can take a chip of it without making a noticeable scar. Maple bark is nice and soft and easy to slice patches off of with a sharp pocket knife. (You might press it until it dries if you get a thin flake, though, else it curls up and makes dissection a pain in the butt!)

Not sure it’s a lichen

I couldn’t take samples of these weird things withough damaging the trees, and testing them in natural settings was out of the question. Due to the darkness of the understory, I couldn’t see much with a naked eye either. Thus it remains a mystery object. The location is well known and could be checked out again if necessary. The host trees are maples.
