On medula, it darkened to a point where I wanted to call it orange, but stopped just short of it.
I’m wondering if it’s this sterile pustulate-sorediate Aspicilia. I’ve seen it called “cf. simoensis”. Maybe.
That assumed stictic acid. I get nothing if I assume atranorin. But thamnolic acid is another option. I wonder if Loxospora pustulata ever grows so happily on rock?? Was it a particularly vivid intense yellow?
Thallus K+ yellow, KC-, C-
Medula K+ yellow, KC+ yellow (maybe – see below), C-
(KC + shows yellow, doesn’t dilute K + yellow easily, unless large amount of C is used).
Is to know where to start! I have vague suspicions which K and C tests would confirm or dismiss immediately. We could try J. Lendemer’s key, but we need (at least) K, C and KC in order to select the correct subkey right at the very top.
Any suggestions, or just a regular gamut?
Would love to see some spot tests! But I’m guessing that’s not in the cards?
But check out grains of sand permanently embedded in thallus.
