I’d say you know a little about Collema!

You have the most amazing gallery of observations. It’s hard to get good experience with Collema… unless you live in a region with lots of limestone like you do. If you say this isn’t C. furfuraceum, then I’m inclined to believe it!

but I ruled out Collema furfuraceum (as well as C. nigrescens) on the
basis of the lack of isidia (even with the full magnification of the
photo I couldn’t find any isidia or isidia-like structure).

But I’m curious how you rule out Collema furfuraceum?
