A less known terricolous lichen from the M. denigrata group, linked to substrates rich in heavy metals. The species was described from anthropogenic localities in industrial regions of western Europe. In the Czech Republic, it has been reported (on hummus and bryophytes in rock crevices) from two natural localities with mineral-rich rocks at higher elevations of the Krkonoše Mts (the Velký Kotel glacial cirque and slopes of Mt Sněžka above the valley of the Rudný brook).
