LICHALP

Acarospora modenensis H. Magn.

Syn.: ?Acarospora engadinensis H. Magn.

Lichenised.

Substrate: siliceous 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 mild-temperate species of siliceous rocks, often found on walls; apparently more frequent in the Western and Southern Alps, but probably overlooked and more widespread elsewhere in lowland areas.
