Probably the rarest genus member in the Czech Republic. Individual findings come even from lower elevations, often from oaks in well-preserved forests in river valleys. Generally, it occurs on bark of deciduous trees in well-preserved open forests or in agricultural landscape, including pond dams. It is rarer than C. cetrarioides and C. monachorum and prefers lower elevations in southeastern part of central Europe as well (Obermayer & Mayrhofer 2007). Alike the other Cetrelia species, C. olivetorum is sensitive to air pollution and its occurrence history in the country is not known, as in the past, it was not always distinguished from other genus members.
