Description

Thallus rather thick, granular to leprarioid, bright yellowish green. Ascomata estipitate, apotecioid, black, up to 0.6 mm high, with a weak greenish pruinon the outside that disappears with age. Capitulum lenticular and up to 0.4 mm diam. Stipe composed of dark brown hyphae, interwoven, 2-3 µm broad. Macedium well developed, black. Asci claviform, with 8 biseriate or triseriate ascospores. Ascospores ellipsoidal, 1-septate, brown, 12-14 x 4.5-6 µm (after Tibell, Nordic Lichen Flora 1: 24. 1999), constricted in the septum, with conspicuous ornamentation composed of  irregular cracks. Chemistry: Thallus K-, C-, KC-, Pd-. It contains rhizocarpic acid, sometimes also usnic acid (Prieto et al., Lichenologist 52(4): 333-335. 2020).

Habitat and distribution: Species that occurs in overhangs or creeks of granitic rocks protected from the rain, normally in shaddy places with high humidity. Broadly distributed in siliceous areas of the Iberian Peninsula, although it is overlooked and it should be found in more provinces.  Locally abundant in the north of Madrid province (Hoyo de Manzanares, Colmenar Viejo), where some populations contain dozens of individuals.
