LICHALP

Timdalia intricata (H. Magn.) Hafellner

Syn.: Acarospora intricata H. Magn.

Lichenised.

Substrate: siliceous rocks, metal-rich siliceous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: on base-rich siliceous rocks in sunny, exposed sites, with optimum above treeline; rarely collected, but perhaps more widespread in the Alps.
