Phaeophyscia nigricans (Flörke) Moberg

Syn.: Lecanora nigricans Flörke, Physcia leptothallina (Vain.) Zahlbr., Physcia nigricans (Flörke) Stizenb., Physcia nigricans (Flörke) Stizenb. var. sciastrella (Nyl.) Lynge, Physcia nigricans (Flörke) Stizenb. var. tremulicola (Nyl.) Lynge, Physcia sciastrella (Nyl.) Harm., Physcia tremulicola Nyl., Physcia tribacella Nyl.

Lichenised.

Substrate: calciferous rocks, bark, lignum, siliceous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a mainly temperate, perhaps holarctic lichen found on a wide variety of substrata, not infrequent, but often overlooked, on isolated trees in lowland areas, reaching however the subalpine belt; the species has been often misunderstood and confused with dark-coloured specimens of Ph. orbicularis.
