Cephalodia 0.5-1 mm diam., ± hemispherical or irregular, with a rough surface, dark reddish brown to black, frequently interspersed amongst the phyllocladia, also on pseudopodetia, containing Stigonema. Pseudopodetia to 1(-2) cm tall, infrequent or absent, erect, simple or sparingly branched, ± tomentose above with ± warted, occasionally incised, squamulose phyllocladia. Anamorph: no information available. Teleomorph: ascomata apothecia, 1-2 mm diam., rather frequent, terminal on pseudopodetia or on basal phyllocladia. Hypothecium hyaline. Chemistry: thallus K+ yellow, KC+ violet, Pd+ faintly yellow, UV+ white (atranorin and lobaric acid).
