It was found on rock outcrops on a steep slope within an acidophilus beech forest, in a locality not situated in the Mediterranean part of Croatia. The siliceous geological bedrock facilitates the occurrence of species such as Bazzania tricrenata (Wahlenb.) Lindb. , B. trilobata (L.) Gray, Dicranella heteromalla , Hedwigia ciliata, Sphagnum quinquefarium (Braithw.) Warnst. and Trichocolea tomentella (Ehrh.) Dumort .. Oystegus tenuirostris is a Circumpolar Boreo-temperate species ( Hill & Preston 1998; Smith 2004), scattered in montane regions throughout Europe ( Frey et al. 2006). The species was recorded for the first time in Croatia, in Golubinjak Forest in Gorski Kotar Region ( Papp et al. 2013a). In SE Europe it is also known from Albania ( Papp et al. 2010a), Bulgaria ( Natcheva et al. 2006), Greece ( Düll 1995), Montenegro ( Dragićević & Veljić 2006), Romania ( Stefănuţ & Goia 2012), Serbia ( Sabovljević & Stevanović 1999) and Slovenia (Martinčič 2003).
