grassland; also found it on the Bulgarian side of Mizor peak. This is the first record in Serbia and also a new locality of this redlisted species for Bulgaria. Formerly, in SE Europe it was only known from Bulgaria, only from the Rila Mts (NATCHEVA and GANEVA 2005). Grimmia caespiticia (Brid.) Jur. It is in the rare (R) category according to the Red data book of European bryophytes (ECCB 1995). Regarded as a subarctic-subalpine element (DULL 1984) it occurs on acidic rocks in the alpine belts of mountains of Europe, Asia and Greenland (NYHOLM 1998). In the western Stara Planina Mts it was found at Crnovrska reka (stream) near Baltaberilovac village, on exposed, black schistose sandstone rocks and under Midzor peak, at the peak of Tupanar, on sandstone rocks at a temporary small pool in subalpine grassland. This is its second occurrence in Serbia, after the first record in Serbia is from the Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005). Previous records are from Montenegro (SABOVLJEVIC and STEVANOVIC 1999), from Bulgaria and Romania (DULL 1984). It is also is recorded in Turkey (DULL 1984). Lophozia ascendens (Warnst.) R. M. Schust. It is in the rare (R) category according to the Red data book of European bryophytes (ECCB 1995). As a boreal, montane leafy hepatic (DULL 1983, 1984) it lives on large, well-decayed logs in constantly humid forests; therefore, it is considered an indicator of old-growth forests. We collected it on decaying wood at Zubska reka (stream) below the hotel of Babin Zub. Lophozia ascendens was found in Serbia for the first time in the Tara Mts (PAPP and SABOVLJEVIC 2002); later we collected it also in Kopaonik National Park (PAPP et al. 2004), and Golija-Studenica Biosphere Reserve is its third locality in Serbia (PAPP and ERZBERGER 2005). In SE Europe it was also reported from Bulgaria, Romania (DULL 1983).
