Ecology: Growing sun-exposed; under conditions which are dry (usually in moss in forested habitats or on slopes). Thallus: Crustose; branches densely aggregated or caespitose. Primary Thallus: Evanescent. Secondary Thallus: Present, of indeterminate growth; stipe 50-120 mm high, .8-1.8 mm wide, grey (to yellowish white), mottled or tainted brown, with intact or perforated wall, 20 µm thick. Upper Surface: Verruculose, byssoid. Ascocarps: Forming apical at the tip of branches or stipes, moderately abundant. Disk: Plane to strongly convex; brown. Conidiomata: Formed on podetia. Pycnidia: With hyaline ostiolar gel. Secondary Metabolites: Atranorin (at least in traces), fumarprotocetraric acid (with Cph-2, plus other unidentified compounds), and protocetraric acid. Spot Tests: Upper surface: K + bright yellow (citrine, lemon), PD + red.
