realized after posting that I didn’t really save them. Can’t figure out how to edit out the Herbarium box(?).
Also, guess I need to get some more up to date references on these type of things…can’t see what the distinctions are. The spores seem to fall within range of both?

Can you try to get some micro pictures of the sulphidia? It won’t help the id at all, but it would always be cool to have more sulphidia photos from Anellaria!
