Got me stumped…

There are so few truly-yellow (not that milky-yellowish-green lichenologists like to call “yellow”) macrolichens — Vulpicida, Letharia, Teloschistes and one or two Flavocetraria, and a Pseudocyphellaria. And this doesn’t look like any of them. Clearly I’m missing at least one!

If you have access to it and are interested, I’d love to know what it looks like underneath, and if it’s white inside. Even better, if it reacts red in lye.
