Ecology: Terricolous; growing sun-exposed. Thallus: Crustose, squamulose; lobes ascending; rounded at the front; branches densely aggregated, scattered, loosely aggregated, or clustered; separate thallus parts 1-4 mm long; 1-4 mm wide. Primary Thallus: Evanescent or persistent. Secondary Thallus: Present, of determinate growth; stipe 20-60 mm high, .8-2 mm wide, grey-green, olive, or brown, mottled, corticate, with intact wall. Thallus Outline: Margin entire or crenulate. Upper Surface: Verruculose or areolated, olive or brown, smooth; not sorediate. Lower Surface: White or brown. Lower Cortex: Absent. Ascocarps: Forming along the margin of scyphi, sparse. Disk: Weakly convex; brown. Conidiomata: Formed on margins of scyphi. Secondary Metabolites: Atranorin and fumarprotocetraric acid, of the following substance class(es): ß-orcinol depsides and ß-orcinol depsidones. Spot Tests: Upper surface: K + bright yellow (citrine, lemon), C –, PD + red.
