Catapyrenium daedaleum has a squamulose thallus without lower cortex, in contrast to the similar C. cinereum, which also has similar ecological requirements and distribution. C. daedaleum also has a boreal-montane to arctic-alpine distribution and grows on bare calcareous soil, humus and on bryophytes. In the past, it used to be scattered at calcareous localities, including small calcareous areas, in the Czech Republic. However, the records require revision. Currently, it is only known from a former limestone quarry near Chýnov in southern Bohemia.
