  Thallus crustose to areolate, effuse, formed by the prothallus and 1) partly by minute round to irregular areolae, ±contiguous and sometimes appearing as a continuous crust and 2) partly by isidia developing directly from the prothallus; isidia usually dominating. Prothallus indistinct to well developed, white to reddish brown. Areolae c. 0.05–0.10 mm wide, adnate, ±isodiametric, plane to weakly convex, medium to dark green, glabrous or rarely pubescent along the margins. Isidia usually abundant, moderately thick, subglobose to cylindrical, medium to dark green, often with a brown tinge, glabrous, simple to branched or sometimes coralloid, often curved, decumbent to ascending. Upper cortex of type 2, 5–15 μm thick. Apothecia common, to 2 mm wide, irregular in outline, usually conglomerate, convex, pale brown to dark reddish brown, immarginate or with an indistinct often slightly paler glabrous or pubescent (especially when young) margin. Proper exciple pale brown. Epihymenium pale brown. Hymenium colourless. Hypothecium pale brown in the lower part, reddish brown above. Ascospores simple, narrowly ellipsoidal, 7–13 × 2–3 μm. Pycnidia not seen.
CHEMISTRY: Cortex and medulla K–, C–, KC–, P–, UV+ blue-white; containing furfuraceic acid (also known as haemophaein or furfuracein).
