Schismatomma pericleum grows on ridged tree bark sheltered from direct rainfall. In the Czech Republic, it grows exclusively on deciduous trees, probably because of substrate acidification in the past. In the less affected areas of Europe, it also occurs on firs and spruces. The species is associated with old-growth forests from lowlands to mountains. It is sparse in central Europe and in the Czech Republic, with almost no recent findings from the northern part of the country.
