Type locality: Sweden, Härjedaten, Ljusnedal par., Mittåkläppen, 1.8 NNW of Djupdalsvallen, on vertical slate rocks facing SW, 1170 m, 2006, Savić 3129 (UPS - holotype).

Barcode: GenBank EU697726, EU697733.

Coordinates: 62°43'56"N 12°27'11"E.

Thallus: crustose, when well-developed thin, minutely areolate, areoles 0.4-0.6 mm wide, irregular and with slightly uneven surface grey to dark greenish grey; sometimes minutely granular, thin, matt or partly immersed and only emerging as blackish green patches; sometimes almost completely immersed (Savić & Tibell 2008: 274).

Photobiont: the areoles of well-developed thalli contain an unidentified green alga; small, almost black, verrucose colonies of the cyanobacterium Nostoc are frequently associated with the thallus containing green algae and may also participate in a symbiotic relationship (Savić & Tibell 2008: 274).

Chemistry: No lichen substances.

Ecology: Data lacking.
