Description: Thallus crustose, thin, smooth, whitish to pale grey, sometimes with a greenish tinge. Apothecia lirelliform, black, 0.5-2.5(-4) x 0.2-0.5 mm, mostly elongate, rarely branched, sessile, with a slit-like to slightly expanded, epruinose disc. Proper exciple dark, carbonized, extending below the hymenium, up to 40 µm thick laterally, up to 85 µm thick in lower part, K-; epithecium olive-green, K+ green; hymenium colourless, 50-75 µm high, hemiamyloid; paraphysoids branched and anastomosing, 1-1.5 µm thick; subhymenium dark brown; hypothecium black, carbonized. Asci 8-spored, cylindrical-clavate, the inner layer of endoascus amyloid in upper part, with a I+ blue ring visible around a small ocular chamber, Varia-type. Ascospores 3-5-septate, the upper cell distinctly enlarged, hyaline but turning brown and verruculose when overmature, (12-)14-20 x 4-5.5 µm, with a hyaline, 1-2 µm thick, gelatinous perispore. Pycnidia immersed, epruinose. Conidia bacilliform, straight, 4-6 x 1-1.2 µm. Photobiont trentepohlioid. Spot tests: thallus K-, KC-, C-, P-, UV-. Chemistry: without lichen substances.Note: an epiphytic species described from Morocco (Agadir), and apparently widespread in the British Isles, where it was frequentlly confused in the past with A. varia, mainly on bark in relatively dry sites near to the coast, also known from France (Finistère). It is not certain that the European samples really belong to this species. To be looked for in Italy, especially in the Tyrrhenian ecoregion.
Growth form: Crustose
Substrata: bark
Photobiont: Trentepohlia
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
Taxon bound to maritime-coastal situations
