Solorina saccata is associated with calcareous substrates from lowland to mountains. In the Czech Republic, it occurs mostly in larger limestone areas. However, it is rare or completely missing in dryer and warmer regions, such as the Pálava Hills. It prefers humus-rich crevices in natural overhanging or vertical rocks, in the dryer areas north-facing or humid ravines. Rarely, the species might also occurs on anthropogenic substrates. It has already disappeared from many historical localities, currently growing at less than 20 sites, e. g., in the Šumava foothills, Krkonoše Mts and its foothills, Jeseníky Mts and Moravský kras (Moravian karst).
