Distribution:
Description: Thallus crustose, thinly episubstratic, granular or areolate, uneven, whitish, grey to green-grey, the granules c. 50 μm thick. Apothecia biatorine, 0.1-0.15(-0.2) mm across, scattered, often immersed in thallus granules, beige, pale pinkish brown, orange-brown or brown, with a flat to strongly convex disc, soon immarginate. Epithecium brownish; hymenium colourless; paraphyses strongly branched and anastomosing up to the upper part, immersed in a gelatinous matrix and resembling excipular hyphae, the apices mostly slightly clavate; hypothecium colourless. Asci 12-16-spored, broadly clavate, broadly clavate, surrounded by a gelatinous, amyloid sheet, with a well-developed, amyloid tholus containing a widely cylindrical axial body and a poorly developed, bluntly conical ocular chamber, more or less Lecanora-type. Ascospores (0-)1-septate, hyaline, falciform or sigmoid, (7-)10-15(-18) x 1.5-2.5(-3.5) μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: mostly foliicolous in the understory of humid forests; in Central Europe on needles of Abies and Picea, elsewhere on leaves and green twigs of Buxus in very humid situations; widespread in Europe, but most common in its western parts, with several records from the Alps outside Italian territory: to be looked for in Italy.
Growth form: Crustose
Substrata: bark and leaves
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
