Ciri dan struktur
Differing from S. impressula in the presence of imbricately arranged and grouped apothecia with orange-yellow pruina along the margin of the disc, reacting K+ carmine-red and in the presence of a secondary tomentum. Primary photobiont cyanobacterial (Nostoc). 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, plane, with their apices orbicular and revolute to involute and their margins entire to crenate, not thickened; lobe internodes (4–)7–10(–15) mm long, (4–)7–9(–15) mm broad; thallus coriaceous. Upper surface pitted to scrobiculate to rugose towards the centre, yellowish-brown with darker apices in the herbarium, with marginal line in the same colour, shiny; surface glabrous, without papillae and pruina, without maculae; marginal cilia present, abundant, fasciculate, light brown to dark brown, about 0.5 mm. Apothecia abundant, laminal, dispersed, often imbricately arranged and grouped, subpedicellated, with pronounced invagination on lower side, up to 3.5 mm diam.; disc red-brown to brown, sometimes greenish-yellow due to the presence of pruina, shiny; margin entire to crenate and hirsute, with white hairs and orange-yellow pruina. Vegetative propagules absent. Lower surface uneven, beige to dark brown towards the centre; primary tomentum dense to the margin, thick (long), spongy, soft, grey-brown to black with paler tips; secondary tomentum present, but sparse, pubescent, up to 30 μm long. Rhizines sparse, black, up to 0.5 mm. Cyphellae 1–20 per cm 2 towards the thallus centre and 41–60 per cm 2 towards the margin, scattered, irregular, cupuliform to urceolate with wide pore, prominent, below the level of the primary tomentum, with the margin erect, cream to brown coloured, without or with tomentum in the lower half; pore (0.5–)0.6–1.3(–2.5) mm diam.; basal membrane pruinose in the appearance, white to pale beige in older part of thallus; K– to K+ pale yellow, C–, KC –, Pd –.
