Micarea erratica (Körb.) Hertel, Rambold & Pietschm.

A characteristic pioneer species on small or recently exposed siliceous stones. It is tolerant to higher iron content in the rock and infrequently passes also on other substrates, such as slowly decaying lying wood. The lichen often occurs in anthropogenic and semi-anthropogenic habitats (typically stones in railways and road margins), but neither is rare in natural habitats, such as open forests and stony slopes. It is a widespread but sparse species.
