I did see this, but couldn’t add anything useful. I’d interpret the tests as K+y, C-, KC-, CK-… consistent with presence of atranorin alone. Unfortunately, this is the least “useful” result, at least as far as using James Lendemer’s preliminary sterile crustose key goes (which is already pretty spotty at best for the west coast). There’s an entire section to his keys devoted to this case. Hmmm. Here are some possibilities… but there are no descriptions and in many cases no photos so there’s just no telling if these are even close

Rinodina poeltiana — blastidiate, not sorediate, on wood/bark in central CA
Pertusaria albescens — large irregular white soralia, central/southern CA

…ow, those are the only two that even come close. Yeah, as I said, no help. We’re just missing some obvious, I’m sure, I just have no idea what!

More pics and chemistry

There are a bunch of spots of this on this particular fence, the largest are around a few inches across, so i took some more pictures and attempted some chemical reactions. Not sure how helpful it is, please let me know what I could improve!

no clue!

Can’t imagine what this is. Looks like a macrolichen, even…
