Verrucaria cryptica (Arnold) J. Steiner

Syn.: Amphoridium crypticum Arnold
Lichenised. Poorly known taxon.
Substrate: calciferous rocks
Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the nival belt (above the lower limit of perennial snow and glaciers)
Note: on compact calcareous rocks and dolomite near and above treeline; a very critical taxon, related to V. hochstetteri s.lat., which needs further study.
