Papp, Beáta; Erzberger, Peter: Contributions to the bryophyte flora of Western Stara Planina Mts (E Serbia)

Part of the data concerning the populations of European redlisted species in Serbian Stara Planina were published also in PAPP et al. (in press). Brachythecium geheebii Milde A moss species listed in the rare (R) category of the Red data book of European bryophytes (ECCB 1995), it is a subcontinental-montane element (DULL 1985) and a European endemism (ECCB 1995). It occurs on shaded, slightly basic rocks in the high mountains of Central Europe and Norway (FREY et al. 1995, DULL 1985). We found it under Babin Zub, on a boulder scree and the basis of great, Permian red sandstone rocks and under Midzor peak on sandstone rock outcrops in subalpine grassland. The species was first recorded in Serbia from the Golija-Studenica Biosphere Reserve (PAPP and ERZBERGER 2005) thus this is the second locality in Serbia. It was reported earlier from Montenegro (SABOVLJEVIC and STEVANOVIC 1999). In SE Europe it has records from Bulgaria, Romania (DULL 1985), Montenegro and Slovenia (PAVLETIC and PULEVIC 1975, ECCB, 1995). Bryum neodamense Itzigs. It is in the rare (R) category according to the Red data book of European bryophytes (ECCB 1995) and is regarded as a subarctic element (DULL 1985). It is reported for the first time from Serbia; in SE Europe it is known from Croatia, Slovenia (DULL et al. 1999) and Bulgaria (NATCHEVA and GANEVA 2005), in the latter only from the Vitosha Mts. Encalypta microstoma Bals.-Criv. et De Not. In the rare (R) category according to the Red data book of European bryophytes (ECCB 1995), this is a subarctic, subalpine species (DULL 1984). According to NYHOLM (1998) it is very rare, confined to the higher mountains of Europe. In the western Stara Planina Mts we found it under Midzor peak, at the peak of Tupanar on sandstone rocks in subalpine
