Synalissa ramulosa grows on natural rock outcrops with periodic water seepage, usually on limestone, more rarely on other substrates, including silicates, rich in or secondarily enriched with calcium ions. In Europe, it is scattered from lowlands to mountains. In the Czech Republic, it is locally abundant in karst areas. Most of its recent localities are in central Bohemia and south Moravia.
