Description: Thallus crustose, poorly evident, endosubstratic to thinly episubstratic and small-granulose, forming small, pale grey to yellowish grey patches. Apothecia biatorine/zeorine, sessile, 0.2-0.5 mm across, with an orange to orange-yellow, flat, epruinose disc and a paler, usually yellow proper margin; a grey thalline margin is sometimes visible only on the lower surface of apothecia. Thalline exciple ecorticate or with a very poorly developed cortex; proper exciple 20-40(-50) μm thick, consisting of radiating, thick-walled hyphae with long and narrow short-ellipsoid cells; epithecium orange, K+ red, C-; hymenium colourless, 55-70 μm high; paraphyses simple, submoniliform, up to 2.5-3 μm wide at apex; hypothecium colourless. Asci 8-spored, cylindrical-clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, (8.5-)10-12.5(-15) x (5-)6-9 μm, the equatorial thickening (“septum”) 3-7 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red, C-. Chemistry: thallus without lichen substances; apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
Note: superficially similar to A. cerinella, but with a different number of spores per ascus. On base-rich bark, often of Populus tremula sometimes on nutrient-enriched twigs of conifers, usually absent from coastal-maritime situations. Some Italian records could refer to A. skii.
