Sticta bicellulata

Ciri dan struktur

Differing from S. pseudoimpressula in the predominantly bicellular spores and the absence of secondary tomentum and the K+ violet (instead of carmine-red) reaction of the apothecial atraquinone. 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, 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 cm 2 towards the thallus centre and 21–40 per cm 2 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 –.
