Has conspicuously red apothecia or pycnidia along the rims, and it is rare at best in California. C. carneola has pale to dark brown pycnidia along the rims, sometimes looking a bit reddish especially if wet, but never conspicuously bright vivid red. Also C. carneola typically has “jagged” or “crown-like” cup margins; your specimen is a particularly good example of this. You say ascospores will also distinguish them? Great! Yes, apothecia should be on the cup margins; check the largest ones, because they might all be pycnidia instead (containing conidia instead of ascospores, and they’re much much smaller).

I’ve read up on Cladonia carneola and the only alternative I can find is C. pleurota, looking at pictures I don’t think it is likely that though. If this ( http://symbiota.org/nalichens/taxa/index.php?taxon=53384 , how do you hyperlink?) is correct, acarospore size should distinguish them easily? These can be found on the cups if correct?

And you’re right that I should of mentioned the spot test in the notes, I recall thinking about it, but must of gotten distracted.

Oh, would you look at that!

I didn’t scroll down far enough to see the last photo! Sorry! Yes, that looks KC+ gold to me, too. C. carneola is looking very good, indeed.

(It might be good, by the way, to mention the spot test in the notes.)

Is the last photo not showing a KC+ gold cortex?

Edit: I read your comment better, what parts do you think would be best to test? Would the base of the stems work?

Crowned cups suggest C. carneola

Chemistry can help verify. C. carneola has usnic acid so should have KC+ gold cortex. But even C. chlorophaea group can have proliferations on the cup margins.
