| Thallus loosely adnate, to 7 cm wide, pale grey to grey. Lobes subcontiguous centrally, becoming linear-elongate, di- or trichotomously branched, 1–3 mm wide, evenly inflated, hollow; margins lacking lateral contacts.

Ascospores 5–8 × 3.5–4.5 µm. Pycnidia common, subglobose. Conidia bifusiform, 5–6 × 1 µm. CHEMISTRY: cortex K+ yellow; medulla K-, C-, KC+ rose, P-. Atranorin, chloroatranorin, physodic acid (major); oxyphysodic acid, 2'-O-methylphysodic acid (minor); alectoronic acid (trace). | ||
