Description: Thallus crustose, episubstratic, minutely granular, dark to pale green, entirely consisting of slightly warted, rarely spinulose goniocysts. Apothecia short-lived, without a proper margin, 0.3-1 mm across, stalked or appearing sessile when crowded amongst goniocysts, turbinate when young, becoming convex to globose, pale flesh-coloured to orange-brown. Proper exciple absent; hymenium lacking gelatine, consisting of asci and abundant, branched and anastomosing, contorted paraphyses not entwining the asci. Asci 8-spored, cylindrical, thick-walled, with a thick I+ blue apex (except for an apical pore). Ascospores (0-)1-septate, hyaline, cylindrical or narrowly ellipsoid, 10-16(-18) x 2.5-4(-5) μm, with rounded apices and a smooth wall. Photobiont chlorococcoid (Leptosira). Spot tests: all negative. Chemistry: without lichen substances.
Note: a widespread but poorly collected species growing on disturbed sandy soil, more rarely on rocks in sheltered to open, often heavy metal-enriched (zinc and lead) habitats, more rarely on bark near fencing wire staples. To be looked for in Italy.
