Note are so important!

My own notes have evolved radically many times over the years. I so wish I’d just been obsessive-compulsive right from the start! But who’s to know how far one is to go 10 years down the line?

You’re right!!

I think my notes may have gotten mixed up. I scoped this briefly as well and it aligns with Ochrolechia as well. Chem tests were K-, C- on thallus and apothecial margins; apothecial discs were K-, C+r (strong) and KC+r. Now that I’m doing more microscopy, sometimes weeks apart from the initial field photos, I guess my organization needs to improve. Thanks for catching!! However, I still don’t see any other ‘original’ notes from this other than what I first referenced, odd!

Could you double check your C test?

This has got to be Ochrolechia. Maybe it’s O. africana with only the medulla C+ pink? All of the Ochrolechia in the region should be C+ pink at least somewhere.
