LICHALP

Calicium montanum Tibell

Lichenised.

Substrate: bark, lignum

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: a recently-described species with a relatively thick, pale grey thallus, short-stalked apothecia with a white pruina, and ascospores with coarse irregular cracks; usually on wood of conifers in the montane belt; probably more widespread in the Alps.
