Obviously I never would’ve considered Myelochroa until you suggested it. But now that you do, it’s clear.

No specimen.

This photo was made long before I was collecting any specimen for ID. Also, it was just after rain, so it’s wet, and as you observed, it’s covered in some sort of slime or something – that’s probably a reason for the color. In fact, it seems the greenest patches are covered in algae.

Glad you came back to this

Is this one of the specimens Jim or I looked at? The color in these photos is very misleading. But now that we’re thinking “Myelochroa aurulenta”, I can totally see it.

No underneath, sorry.

But the entire tree was covered with this lichen and it was hard to see separate rosettes. There were some wet spots on the lichen, but I thought it was supposed to be like that, not knowing better: the pictures were taken after the rain.

Odd form of Flavoparmelia?

Not sure what else it can be. Looks a bit “straggly”, but then it looks a bit unhealthy, covered with some sort of algal slime or something. Is it black underneath with rhizines becoming very small or absent near the edge where it’s brown? Would expect K- C- KC+ pink (in medulla).
