Descriptions
Thallus crustose, effuse, scurfy-furfuraceous, whitish-grey or lacking, in patches 1-5 diam., K-, saxicolous. Apothecia small, crowded, 0.3-0.5 mm diam., deformed-angular through mutual pressure, solitary fruits rounded, sessile, concave at first, becoming ± convex, disc deep yellow or orange, matt, margins concolorous with disc or paler, entire, most obvious in young fruits, occluded with age. Ascospores biseriate, ellipsoid with rounded ends, straight, 2-locular, 10-16 × 5-7.5 µm, septum c. ¼ to ⅓ length of spore. Chemistry: Emodin, parietin, xanthorin, fallacinal.
Thallus crustose, scurfy-granular, 0.1 mm thick, grey-brown to black, ± areolate, areolae 0.05 mm diam., separated by shallow to deep cracks, uneven-verrucose, K-, in irregular patches 1-5(-8) cm diam., saxicolous. Apothecia sessile, scattered to crowded, rounded or contorted through mutual pressure, 0.1-0.5(-0.8) mm diam., disc shallowly concave at first then plane, becoming distinctly convex and immarginate with age, dull reddish-orange to bright cinnabar-red, matt, margins thin, entire, concolorous with disc or paler, persistent or occluded with age.
