LICHALP

Naetrocymbe saxicola (A. Massal.) R.C. Harris

Syn.: Arthopyrenia saxicola A. Massal., Leiophloea saxicola (A. Massal.) Riedl, Naetrocymbe massalongiana (Hepp) R.C. Harris, Pyrenocollema saxicola (A. Massal.) Coppins, Sagedia massalongiana Hepp

Lichenised.

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

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: an early coloniser of hard, steeply inclined surfaces of calcareous rocks, on surfaces which rapidly dry out after rain, often with Hymenelia coerulea. This species is clearly lichenised, with Trentepohlia.
