Budapest, Pf 222, Hungary;pappbea@bot.nhmus.hu "Belziger Str. 37, D10823 Berlin, Germany; erzberger@erzfisch.de During the bryophyte investigation carried out in July 2005 in Western Stara Planina Mts (E Serbia) altogether 322 bryophytes (62 liverworts and 260 mosses) were recorded. Among them 27 are reported for the first time in Serbia (Gymnocolea inflata, Gymnomitrion concinnatum, Jungermannia pumila, Marsupella emarginata, Radula lindenbergiana, Ricciagougetiana, Tritomaria exsecta, Bryum neodamense, Cynodontiumgracilescens, C. strumiferum, Dicranum spadiceum, Encalypta microstoma, Grimmia elatior, G. torquata, G. unicolor, Hypnum cupressiforme var. subjulaceum, H. hamulosum, Lescuraea saxicola, Orthotrichum urnigerum, Paraleucobryum sauteri, Philonotis arnellii, Pohlia bulbifera, P. longicolla, P. nutans var. schimperi, Racomitrium lanuginosum, Schistidium papillosum, Timmia bavarica); one species (Cynodontium tenellum) collected on the Bulgarian side of Midzor peak is new record for Bulgaria. 7 species from the Western Stara Planina Mts are included in the Red data book of European bryophytes (ECCB 1995), i.e. Brachythecium geheebii, Bryum neodamense, Encalypta microstoma, Grimmia caespiticia, Lophozia ascendens, Paraleucobryum sauteri, Pseudoleskea saviana. All of these but the last one (being in the regionally threatened (RT) category) are rare (R). Furthermore, 12 liverwort and 34 moss species are of national conservation and protection interest in Serbia or Bulgaria. Key words: bryophyte flora, Bulgaria, new and redlisted species, Serbia, Western Stara Planina Mts INTRODUCTION Although the checklists of the bryophytes of Serbia (SABOVLJEVIC 2000^, SABOVLJEVIC and STEVANOVIC 1999) were published only very recently, thanks to intensive field work conducted in the country, mainly in protected areas, many new records have been revealed (e.g. SABOVLJEVIC 2000b, 2003^, b, 2006, SABOVLJEVIC and STEVANOVIC 2000, BLOCKEEL et al. 2003, PAPP and SABOVLJEVIC 2001, 2002, PAPP and ERZBERGER 2005, PAPP et al. 2004, 2006, SABOVLJEVIC and CVETIC 2001, 2003, VELJIC et al. 2001, PÓCS etat 2004, CVETIC and SABOVLJEVIC 2005).
