bly has a scattered distribution, and it is known from few localities in Bulgaria, Croatia, Romania, Slovenia and Turkey (SABOVLJEVIC and NATCHEVA, in press). Cololejeunea rossettiana, Leiocolea badensis and L. bantriensis are tiny leafy liverworts and are probably under-recorded. However, the first one is widespread in the region, with records in all countries except Bosnia-Herzegovina, Macedonia and Turkey (SABOVLJEVIC and NATCHEVA, in press). The last two are sporadically present in a few countries of the region. Cololejeunea rosettiana was found in Serbia in Petnica region (PAPP and SABOVLJEVIC 2001) and in Tara National Park (PAPP and SABOVLJEVIC 2002), while Leicocolea badensis was collected in Tara National Park and Kopaonik Mts (PAPP et al. 2004). Leiocolea bantriensis was collected in Tara National Park, Kopaonik Mts (several localities) and the Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005). According to these data, L. bantriensis seems to be less threatened, at least in the protected areas investigated. Amphidium mougeotii is a circumpolar montane species becoming rare in Europe towards the Southeast. It was not expected at such low altitude in Southern Europe. Due to its isolation, the population deserves special conservation attention. However, in higher mountains of Serbia it might be more frequent, as e.g. in Stara Planina (PAPP and ERZBERGER, numerous unpublished records). Amblystegium confervoides occurs in some neighbouring countries (e.g. Bosnia-Herzegovina, Bulgaria, Croatia, Romania and Slovenia), but former records in Serbia are very few. It was published without precise locality by GAJIC et al. (1991) and MARTINCIC (1968). In the Djerdap National Park many suitable growth sites are present (shaded calcareous rock) and numerous populations were registered, some even with sporophytes. Anomodon longifolius, an Eurasian boreo-temperate species (SMITH 2004), is a tiny, easily overlooked, pleurocarpous moss. It has recently been recorded from W Serbia (PAPP and SABOVLJEVIC 2001) and this is its second record. At both locations the species grows under similar conditions on shadowed calcareous rock. The first record of the European red-listed Anomodon rostratus in Serbia was from Petnica, W Serbia (PAPP and SABOVLJEVIC 2001), the second in Tara National Park (PAPP and SABOVLJEVIC 2002) and the third in Mt Avala (C. Serbia; SABOVLJEVIC and CVETIC 2003). The fourth record in Serbia is reported here. Dicranella schreberiana, a circumpolar boreo-temperate species according to SMITH (2004), was previously only mentioned by MARTINCIC (1968) without precise locality. Didymodon ferrugineus is known to be present in Serbia sporadically. It was recorded recently from Tara National Park (PAPP and SABOVLJEVIC 2002) and Kopaonik Mts (PAPP et al. 2004). This is its third recent record in Serbia.
