Also know as powdered funnel lichen- pretty far South for you to find this spp. but from what I can key this looks to be correct. Beautiful observation!

These are not actually sorediate

If you look closely, Drew, you can see that the “powder” is actually small corticate lumps / microsquamules. This is pushing it for C. pyxidata, I think, but I think it’s the best name for it. Sometimes it’s hard to draw a clear line between C. chlorophaea group (with minute soredioid corticate granules) and C. pyxidata (with full-on microsquamules and corticate tiles). Note that C. cenotea (in addition to being truly sorediate/powdery) has cups with a distinctive curled-in mouth and are distinctly perforate in the “throat”. As you say, C. cenotea is a more northern species, but I see at least one (questionable) report from the high mountains of North Carolina. Otherwise, it is unknown south of the Great Lakes and New England (at least in the east).

Thanks Drew!

That is interesting. On the same log were spiky Cladonia cristatella – too young to have the red on the top yet. Lots of complexity in the ecosystem here!
