LICHALP

Physcia tenella (Scop.) DC.

Syn.: Borrera tenella (Scop.) Ach., Hagenia tenella (Scop.) De Not., Lichen tenellus Scop., Parmelia stellaris (L.) Ach. var. tenella (Scop.) Spreng., Parmelia tenella (Scop.) Ach., Physcia adscendens (Fr.) H. Olivier var. tenella (Scop.) H. Olivier, Physcia stellaris (L.) Nyl. var. tenella (Scop.) Nyl., Physcia subobscura (Nyl.) Nyl.

Lichenised.

Substrate: bark, lignum, 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: a mainly temperate species. Its separation from Ph. adscendens is not always clear: very characteristic specimens, hardly referrable to Ph. adscendens, are most common in the submediterranean belt in semi-natural situations. Some records might be due to confusion with young or poorly developed specimens of Ph. adscendens.
