Thallus thin, minutely granular-warted or wrinkled, without cracks, greyish-green to greyish-brown, prothallus not apparent. Soralia few to numerous, at first discrete, punctiform, ≤0.2 mm diam., often becoming confluent, green-yellow, soredia rather loosely arranged, efflorescent. Soralia C+ red (weak but can be detected as a spot reaction), K–, KC-, Pd–, UV– (gyrophoric acid).

Anamorph: not observed.

Teleomorph: ascomata apothecial. Apothecia rare, <0.3 mm diam., sessile, disc dilute to dark red-brown (K–, N–) or pale green (K–, N+ purple) or a combination of both pigments (as in S. chlorococcum); paraphyses 1.5-2 µm wide, apices ± clavate. Ascospores 25-35 × 2.5-3 µm, 3- to 7-septate, sigmoid, spirally twisted in the ascus.
