Gyalecta jenensis (Batsch) Zahlbr.

The most common Gyalecta of the Czech Republic, locally distributed across numerous regions of the country. It is missing only in the most extensive lowlands and the highest siliceous mountains. It is a lichen naturally growing on moderately shaded to shaded, vertical or overhanging limestone or Ca-enriched siliceous rocks. On acidic substrates, e.g. on sandstones, its presence safely indicates higher calcium content. It can occur in crevices of acidic rocks, in the parts with leaking water that had passed through Ca-rich layers. The species can be found also on mortar or concrete in some anthropogenic, microclimatically suitable habitats, such as old stone walls, calcareous rocks at castle ruins or old bridges. In the localities, where it is abundant, it sometimes passes to humus or decaying bryophytes. Consequently, it may be mistaken for rarer, mountain terricolous taxa.
