LICHALP

Squamarina concrescens (Müll. Arg.) Poelt

Syn.: Lecanora concrescens (Müll. Arg.) Zahlbr., Lecanora sublentigera Jatta, Placodium concrescens Müll. Arg.

Lichenised.

Substrate: calciferous soil, calciferous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: an often misunderstood species with a southern distribution centered in dry areas, found on base-rich clay soil in clearings of grasslands and garrigues, but also on weathered or fissured rocks; in the Alps it mainly occurs in xerothermic stations.
