Myriolecis pruinosa is a typical species of vertical to overhanging limestone rocks. However, it may also grow on human-made substrates and basic silicates. In Europe, the species is locally common in some areas rich in limestones, especially in the Mediterranean or Western Carpathians. The only known Czech locality, the Kotouč hill near Štramberk, was also a part of the west-Carpathian range. Unfortunately, the species has probably disappeared here due to the extensive limestone mining.
