I do like the laxa description though “Typical specimens of Lecanora laxa are characterized by large, basally strongly constricted and flexuose apothecia.” It’s closer than hagenii anyway.

If these are laxa, then the previous ones we thought might be hagenii are possibly also laxa…both specimens are rather greenish, hagenii is meant to be grey or brown.

For (most) Lecanora you need microscopy

Nothing else will do. :( Species of that genus produce all sorts of strange substances in various places, so that observing where granules and crystals occur, and what they’re soluble in becomes critically important. There are a few that are so distinctive you can confidently id them at a glance, but those are the exception.

Closer to laxa than hagenii?

Doesn’t have that apparently ragged apothecial margin of hagenii, and its so green. If the spot tests on these are all negative, there must be some other way to separate them.

I guess these qualify as “flexuose”, too.

Definitely Lecanora

Doesn’t look quite like anything I know, though. I want to say it’s close to L. hagenii or L. laxa.
