Description: Thallus crustose, episubstratic, dark grey to blue-black, thin, continuous or rimose-areolate, often granulose-blastidiate. Apothecia lecanorine, sessile, 0.4-0.7 mm across, with a black, flat to convex disc and a prominent, persistent, smooth to rarely granulose thalline margin. Thalline exciple corticate, the cortex paraplectenchymatous, up to 30 μm thick, of 5-10 μm wide cells I-, K+ violet; epithecium blue-grey to bluish-black, K+ violet; hymenium colourless, 70-85(-100) μm high; paraphyses simple to sparingly branched in upper part, the apical cell strongly swollen and 3-5 μm wide; pigment located among the tips of paraphyses; hypothecium colourless to pale yellow, to 70 μm high. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, pale brown to almost colourless when young, (15-)17-20(-22) x 7-9(-10) μm, Mischoblastia-type, the wall smooth, without a well-developed torus, the ontogeny of type A (apical wall thickening after the early septum formation). Photobiont chlorococcoid. Spot tests: thallus K+ violet, C+ violet, P-, N+ violet. Chemistry: thallus without lichen substances, except a K+ and N+ violet pigment in cortex.Note: a mild-temperate to Mediterranean lichen found on dust-impregnated bark of isolated trees, especially Populus, Fraxinus, Juglans and Ulmus, often on the basal parts of trunks; certainly declining, and presently extinct in several regions, probably due to the disappearance of unpaved roads during this century. It is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
