LICHALP

Aspicilia mastrucata (Wahlenb.) Th. Fr.

Syn.: Lecanora lyckselensis H. Magn., Lecanora mastrucata (Wahlenb.) Ach., Lecanora subreagens H. Magn., Lichen mastrucatus Wahlenb., Sagedia mastrucata (Wahlenb.) A. Nordin, Savić & Tibell

Lichenised. Poorly known taxon.

Substrate: siliceous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a species found on siliceous to weakly calciferous rocks, mostly above treeline, belonging to a poorly understood complex, reported from Northern Europe, upland areas of Central Europe and Turkey; it is however dubious that the samples from the Alps belong to A. mastrucata in the strict sense.
