This apparently looked different enough from the standard Sticta beauvoisii that I collected a fragment for later ID. Turns out it really was different — the yellow medulla, far from just being a sign of a dying thallus!, is actually an anthraquinone (K+ deep wine-red). Makes it the rare Sticta fragilinata. I don’t know if the lobulate margin is typical of the species or now.
