Let’s just write off the apparent C+ y/o reaction to the cortex breaking down and algae showing through after the C+ pink reaction fades.

from same piece of wood, but I wonder if it is the same thing? No apothecia present, but there is soredia.

possible sorediate area in the middle? I’ll admit, tough to tell. As for the other genera, Pycnora, Xylospora, Toensbergia, etc…none seemed to fit very well, based on the images/chemistry, but I am not really sure.

I think you’re on the right track

But I’m concerned that there are no soredia visible. (Do you see some I’m missing?) You might consider one of the crustose Hypocenomyce (sensu lato), e.g. Pycnora or… I forget the names of the new genera, sorry!
