Fissidens exilis is a species newly recorded for Serbia recently in Mt Avala (SABOVLJEVIC and CVETIC 2003). It has also been published from the surroundings of Belgrade by GRDOVIC (2005). This is its third record in Serbia. In a similar way, our record of Fissidens viridulus is the second record in Serbia, since it was also found in Mt Avala (SABOVLJEVIC and CVETIC 2003). It has not been assigned a threat status in SABOVLJEVIC et al. (2004), but obviously it qualifies as data deficient (DD). Orthotrichum obtusifolium appears to be extremely rare in Serbia (PAVLETIC 1955, SABOVLJEVIC et al. 2004). Recently it was reported from Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005). In Djerdap National Park it was recorded on several trees. According to the observations in Central Europe, this species is generally more frequent in calcareous areas. The European red-listed Rhynchostegiella teneriffae was first recorded in Serbia by PAPP and SABOVLJEVIC (2001). It was known from Bosnia-Herzegovina and Slovenia. This is the second record of this rare European species in Serbia. Tortula papulosa, first recorded in Serbia recently (SABOVLJEVIC 2000/?), seems to be in range expansion within the region since many new records appear recently. Tortula virescens has rarely been recorded in Serbia. There are also several other species, which were reported only from a few localities in Serbia. Cephaloziella divaricata, Cinclidotus riparius, Hedwigia ciliata var. leiicophaea, Pohlia lescuriana, Pohlia lutescens were reported for the first time in Serbia from the Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005). Their 2nd locality is in Djerdap National Park. Bryum rubens was found around Petnica, W Serbia (PAPP and SABOVLJEVIC 2001 ). Its 2nd locality is reported here from Djerdap National Park. Ditrichum pusillum was reported from the surrounding of Belgrade by GRDOVIC (2005). Its 2nd locality is in Djerdap National Park. Schistidium pruinosum was found for the first time in Serbia in Tara National Park (PAPP and SABOVLJEVIC 2002). Its 2nd locality is reported here. Fissidens pusillus was recorded in Petnica, W Serbia (PAPP and SABOVLJEVIC 2001) and the Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005). Its 3rd locality is in the Djerdap National Park. Grimmia tergestina reported from Kopaonik Mts (PAPP et al. 2004) and Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005). This is its 3rd locality in Serbia.
