It grows on acid siliceous rocks and stones, from exposed to partially shaded ones. In Europe, it has been reported mainly from the northern part of the continent, otherwhere it has been seen relatively rarely. However, it may be partly caused by confusion with other similar taxa. For example, recently published data associated with the name A. laevata from the Brdy Hills actually belong to this species (cf.; Malíček et al. 2018). Only a limited amount of verified records comes from the Czech Republic. It is abundant in the screes in Brdy, otherwise it probably occurs rarely at middle or higher elevations.
