Distribution:

Description: Thallus crustose, thinly episubstratic, whitish, finely granulose, sometimes evanescent. Apothecia biatorine, 0.1-0.15 mm across, whitish to pale pink-coloured when young, very pale brown at the end, from the beginning strongly convex and immarginate, sometimes subglobose and tuberculate, often white-pruinose. Proper exciple of radiating, branched and anastomosed hyphae; epithecium colourless to pale yellowish brown, without granules or with scattered granules dissolving in K, never forming a distinct layer; hymenium colourless, I+ blue; paraphyses scarce, strongly branched and anastomosing, immersed in a gelatinous matrix and resembling excipular hyphae, not swollen at apices. Asci 8-spored, cylindrical-clavate, with a K/I+ blue apical dome penetrated by a narrow, K/I- apical cushion surrounded by a narrow, deeply K/I+ blue zone, the wall K/I- but surrounded by a I+ red-brown and K/I+ blue outer layer, the ocular chamber small, Biatora-type. Ascospores 3-5-septate, hyaline, 24-30 x 1.2-1.5 µm strongly curved at least at one end, spirally twisted in the asci. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.

Note: on bark of deciduous trees in humid forests along creeks; widespread in Europe but rarely collected, with a few records from the Eastern Alps (Austria, Slovenia), but easy to overlook and perhaps more widespread in the Alps: to be looked for in Italy.

Growth form: Crustose

Substrata: bark

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)
