A small microlichen of humid habitats, usually reported from inundated acidic stones in springs and running water. The species resembles the related G. fritzei in appearance and ecology (Vězda 1978). However, it is found also outside the direct reach of water, e.g. on pebbles in alluvial deposits and repeatedly in semi-anthropogenic habitats such as sandpits or road cuts, where it can grow as a pioneer species on small stones on moist sandy soil with*Micarea lithinella* and lichens from the Trapelia genus. In the Czech Republic, this partially overlooked lichen has been reported from the Krkonoše Mts, the Orlické hory Mts, the Šumava Mts, the Jeseníky Mts and the Králický Sněžník Mts.
