). Stipe absent. Thallus irregular to suborbicular, up to 10 cm diam., moderately branched, with 3-5 branches per 5 cm radius, branching polytomous; lobes laciniate to flabellate, adjacent, involute to weakly canaliculate, with obtuse to truncate, plane to revolute apices and their margins entire, slightly thickened; lobe internodes (3-)6-8(-20) mm long, (4-)7-10(-13) mm broad; thallus coriaceous. Upper surface pitted to shallowly scrobiculate to rugose, light brown with darker apices in the herbarium, shiny, with the marginal line in the same colour; surface glabrous, without papillae and pruina, without maculae; marginal cilia present, about 0.5 mm, abundant to scarce, white to golden brown, agglutinated. Apothecia scarce, laminal, dispersed, subpedicellate, with pronounced invagination on lower side, up to 2.5 mm diam.; disc orange-brown (in young apothecia) to brown or greenish (in older apothecia) due to the presence of pruina, along the margin with an orange pigment; margin hirsute, with white to golden brown hairs. Vegetative propagules absent. Lower surface uneven, beige to light brown; primary tomentum dense to the margin, thick, but thinner towards the margin, spongy, soft, white to dark brown often with brown tips; secondary tomentum absent. Rhizines absent. Cyphellae 1-10 per cm2 towards the thallus centre and 21-40 per cm2 towards the margin, abundant, scattered, rounded to irregular, urceolate with wide pore, prominent, remaining below the level of the primary tomentum, with the margin raised and involute, white to brown coloured, without or with tomentum at the base; pore (0.25-)0.5-1(-1.5) mm diam.; basal membrane pruinose in the appearance, white, K- to K+ yellow, C-, KC-, Pd-. Medulla compact, white with yellow spots, K+ pale yellow, C-, KC-, Pd-. Apothecial margin (ring around disc) and epihymenium K+ violet. No substances detected by TLC in the thallus, unidentified anthraquinone in the apothecia.

Remarkably, the taxa form a sister group relationship, denoting the presence of apothecial anthraquinones as a synapormorphy, although apparently, the two species diverged to the point that the anthraquinones are of a different nature, as indicated by their different K+ reaction.
