I just sent this specimen to James

At least I think it was this specimen… :)

I was, needless to say, completely stumped by it, even in with specimen in hand.

Jim was stumped with this one. He is still pondering the options

Oh, I think I’ve got it!

Maybe it’s a Stereocaulon. Um. One of the crustose species, maybe? Oh phooey, I don’t know.

The only rock-dwelling isidiate gray species with K- and C- in Lendemer’s sterile crust key is Loxosporopsis corallifera… but it’s only known from the Pacific coast.

Maybe it’s some sort of weird form of a Pertusaria or Ochrolechia.

Just tried K on this.

Surface of isidia is K+ very light green (I know there is officially no color result like this but that’s what it looks like to me). Medula changes color just a tad too. The most pronounced color – dark green – is where I cut through thallus, so the inner space of cortex where cut, however thin, stands out for its dark color against other parts of lichen.

Okay, don’t panic…

What about K? There are relatively few sterile isidiate crusts, we should be able to narrow this down quickly…

No response to C :-((

I’m only slightly better off than you…

I know where to start guessing, at least! :) Try Ochrolechia yasudae… is it C+ red by any chance? (Would be extremely unsubtle if my guess is right.)

I don’t even know where to start guessing :-(
