A species characteristic for humid, shaded calcareous rocks. For a long time, it had been only known from three Moravian localities, from the Pálava Hills, Podyjí, and Moravský kras (Vězda 1958). In the last-mentioned locality, its occurrence has been lately confirmed (Halda et al. 2017). Relatively recently, the lichen has been found also in Český kras (Vondrák et al. 2007).
