Managed to expose lower surface – it’s greenish (no cortex?).

No rhizines. It was very hard to expose decent surface of medulla (it’s just so thin), but when I got it I applied KOH and got K+brown (can’t define it better).

If it’s that closely-attached, then let’s dust off Hyperphyscia syncolla after all…

It’s not wet – the rains passed at night though.

But by the time I took this photo it was reasonable dry (although I am sure lichen contained some moisture from overnight). Lower surface is hard to discern – the thing is literally welded to smooth bark – but in places I managed to poke through it’s white, it seems.

Not convinced

I’d have said this was Hyperphyscia except that the lobes are so broad. Can it be Phaeophyscia? It just doesn’t look pale enough to be Physcia. But it wouldn’t be the first time I was wrong! Is it wet, by any chance?

lower surface appears to be white but hard to peel off the bark.
