Aspicilia intermutans (Nyl.) Arnold

Syn.: Aspicilia ammotropha Hue, Aspicilia trachytica Flagey non (A. Massal.) Arnold, Aspiciliella intermutans (Nyl.) M. Choisy, Lecanora ammotropha (Hue) Zahlbr., Lecanora intermutans Nyl.
Lichenised.
Substrate: siliceous rocks
Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)
Note: on more or less base-rich siliceous rocks wetted by rain. This is one of the most frequent silicicolous Aspicilia of Mediterranean Europe; most of the records from the Alps, especially those from high altitudes, are likely to refer to A. cinerea, A. prestensis, A. spermatomanes, and Aspilidea myrinii.
