Barbilophozia barbata is relatively common at lower elevations in mountainous regions of Poland. In the Tatra Mountains (Górski & Váňa 2014), most B. barbata populations (89% of those described) are found in the altitudinal belt, up to 1600 m above sea level (a.s.l.). Barbilophozia barbata is rarely found at higher altitudes. It has been described at only four localities above 1900 m a.s.l. (sZweykowski 1960, duda & Váňa 1985). 2. Campylopus flexuosus (Hedw.) Brid. Author: B. Fojcik ATMOS Fc-69: S Poland, Silesian Upland (Wyżyna Śląska), Rybnik Plateau (Płaskowyż Rybnicki), Rybnik town, district Popielów, 50.04532878°N, 18.5134528°E, rotten log in herb vegetation near the edge of deciduous forest, leg., det. B. Fojcik, 7.04.2016 (KTU). Campylopus flexuosus is a Polish bryoflora species that, although rare, is considered to be spreading; it has been identified at many new sites in recent years (steBel 2007, 2015, 2016). Campylopus flexuosus occurs mainly in southern Poland, along the Sudeten-Carpathian arc, and only a few populations are located in central and northern Poland (rusińska 1995, SteBel 2007, 2015). The species usually grows in forests on humic and mineral soil. In general, Campylopus flexuosus has a sub-oceanic distribution (düll 1984). Campylopus flexuosus is partly protected in Poland and numbered among threatened mosses of undetermined threat (category I, Żarnowiec et al. 2004). It is the first locality of this species from the Silesian Upland. 3. Conocephalum salebrosum Szweykowski, Buczkowska & Odrzykoski Authors: H. klama, a. salacHna ATMOS Gd-33: S Poland, Beskid Żywiecko-Orawski Mts, Wielka Racza group (Grupa Wielkiej Raczy), Silesian Province, Żywiec County, Soblówka village, valley of Cichy potok stream, 49.42389°N, 19.13556°E, alt. 700 m a.s.l., on wet soil on the bank of the stream, leg., det. H. Klama, A. Salachna, 23.09.2011, ster. (herb. H. Klama). Conocephalum salebrosum was first described in 2005 (sZweykowski et al. 2005). Thus, all plants collected before 2005 and identified as C. conicum should be reconsidered. Conocephalum salebrosum is a lowland mountain liverwort species and is common in Poland, found throughout the country, mainly in wet places. In the mountains, C. salebrosum can grow even above 1000 m a.s.l. (sZweykowski et al. 2005, Górski & Váňa 2014). This thallose plant has been identified in some regions of the Beskidy Zachodnie Mountains (sZweykowski et al. 2005, wajda & klama 2014). This is the second locality of C. salebrosum in the Beskid Żywiecko-Orawski Mountains (steBel et al. 2011). 4. Didymodon spadiceus (Mitt.) Limpr. Authors: B. Fojcik, r. ZuBel, G. Vončina ATMOS Gf-09: SE Poland, Eastern Carpathians (Karpaty Wschodnie), Sanocko-Turczańskie Mountains (Góry Sanocko-Turczańskie), Suchy Obycz massive, Kamionka river valley (called Dolina Niemiecka valley), Podkarpackie Province, north of the settlement of Arłamów, 49.61872°N, 22.64158°E, alt. 427 m a.s.l., wet stones in the stream in beech forest, leg., det. B. Fojcik, R. Zubel, G. Vončina, 12.09.2015, conf. A. Stebel (KTU, LBL, SOSN). Didymodon spadiceus is a calcicole and hygrophilous moss that usually grows on base-rich rocks and tree boles adjacent to fast-flowing streams and rivers (dierssen 2001, smitH 2004). In Poland, scattered populations of D. spadiceus are mainly found in mountain regions (sZaFran 1957). Didymon spadiceus is classified as a sub-montane species (steBel 2006) and has been reported to occur in the Krakowsko-Częstochowska Upland (sZaFran 1957). It is the first locality of D. spadiceus in the Sanocko-Turczańskie Mountains. 5. Eucladium verticillatum (Hedw. ex Brid.) Bruch & Schimp. Authors: B. Fojcik, r. ZuBel, G. Vončina ATMOS Gf-09: SE Poland, Eastern Carpathians, Sanocko-Turczańskie Mountains, Suchy Obycz massive, Kamionka river valley (called Dolina Niemiecka valley), Podkarpackie Province, north of the settlement of Arłamów, 49.61427°N, 22.641°E, alt. 433 m a.s.l., on dripping cliff encrusting with lime deposits (wellhead in beech forest), leg., det. B. Fojcik, R. Zubel, G. Vončina, 12.09.2015, conf. A. Stebel (KTU, LBL, SOSN). Eucladium verticillatum is a calcicole hygrophilous species that usually grows as dense tufts encrusted with calcareous matter (dierssen 2001, smitH 2004). Eucladium verticillatum has a sub-mediterranean distribution (düll 1984) and, in Poland, has only been identified at one southern site (sZaFran 1957). Eucladium verticillatum has been reported at the Gorce Mountains (steBel & cZarnota 2012), Pieniny Mountains (steBel et al. 2010) and Krakowsko-Częstochowska Upland (Fojcik 2011), among other sites. It is the first locality of this multizonal mountain species (steBel 2006) in the Sanocko-Turczańskie Mountains, as well as in the south-eastern part of Poland. 6. Frullania dilatata (L.) Dumort.

According to the literature, F. dilatata has been found throughout Poland (sZweykowski & koźlicka 1977, sZweykowski 2006). From the Pojezierze Lubuskie, F. dilatata was mentioned in old floras as “frequent” (warnstorF 1885, torka 1904). In the Pojezierze Lubuskie region, F. dilatata has recently been found at numerous localities, but the populations are usually of small size. In Pojezierze Lubuskie, F. dilatata often grows on the bark of various species of deciduous trees and shrubs with subneutral bark reactions (e.g., Padus avium and Acer platanoides), but has also been found growing on trees with more acidic bark, especially Alnus glutinosa and Betula pendula. Frullania dilatata mostly grows in epiphytic bryophyte vegetation in communities from the Orthotrichetalia Hadač in Klika et Hadač 1944 order (class Frullanio dilatatae-Leucodontetea sciuroidis Mohan 1978), and has rarely been noted on trees on the forest edges in nitrophilic communities from the alliance Xanthorion parietinae Ochsner 1928 (class Physcietea Tomaselli & De Micheli 1952). 7. Hamatocaulis vernicosus (Mitt.) Hedenäs Author: P. Pawlikowski ATMOS Bf-12: NE Poland, Masurian Lake District (Pojezierze Mazurskie), Warmia-Masuria Province, Giżycko County, Kruklanki commune, SE from the Borecka Forest (Puszcza Borecka), SW of the village of Możdżany, 54.07287°N, 22.00658°E, small minerotrophic fen surrounded by agricultural land, desiccated due to intensive drainage by newly renovated drainage ditch, a few small patches (covering a to- 34 Piotr Górski et al. tal area of ca. 0,5 m2) in a deteriorating sedge-moss vegetation overgrowing with trees and shrubs, along with Sphagnum teres and Calliergonella cuspidata, not. P. Pawlikowski, 10.08.2013. Hamatocaulis vernicosus is a species occurring primarily in very wet rich fens (dierssen 2001, sZcZePański 2010), listed in Annex II of the European Union Habitat Directive (European Directive 92/43/ EEC – Council... 1992). Hamatocaulis vernicosus occurs throughout Poland and, apart from the young post-glacial landscape of northern Poland, the species is threatened with extinction (steBel 2012). In the Warmia and Masuria Province, its distribution is patchy, but was previously locally abundant (łacHacZ & olesiński 2000, łacHacZ & Pisarek 2002, sZcZePański 2010, W. Pisarek unpubl. from the years 1995-2016, M. Szczepański unpubl. 2000–2016). In the Borecka Forest (a microregion within the Ełk Lakeland), H. vernicosus was recorded in three mires in the south-eastern part of the forest complex (koppe & koppe 1931, 1937). 8. Harpanthus flotovianus (Nees) Nees Author: H. klama ATMOS Gd-69: S Poland, Western Tatra Mts, Dolina Pyszniańska valley, Babi Potok stream, below Żleb Babie Nogi gully, alt. 1320 m a.s.l., on wet soil on the escarp of the stream, leg., det. H. Klama, 7.09.1984, ster. (herb. H. Klama). Harpanthus flotovianus is a subalpine-alpine species that is very rarely found in Poland. Harpanthus flotovianus has been reported in the Sudetes (Karkonosze and Góry Izerskie Mts), Tatra Mountains, Beskid Żywiecko-Orawski Mountains and Gorce Mountains (klama 1996, mierZeńska 1994, sZweykowski 2006). Some relict populations of H. flotovianus have been reported in the northern Polish lowland (sZweykowski 2006). In the Polish part of the Tatra Mountains, four populations of H. flotovianus were recorded in the western parts (Górski & Váňa 2014). Harpanthus flotovianus grows in wet habitats, mainly along streams. 9. Pohlia ludwigii (Spreng. ex Schwägr.) Broth. Authors: P.

In Poland, P. ludwigii has been reported in the Tatra and Karkonosze Mountains (see references in GórSki 2015). From personal studies conducted by the first author between 2002 and 2014, P. ludwigii was identified as a common species in the Polish and Slovakian Tatra Mountains (in Slovakia, P. ludwigii is categorized as NT-endangerment; kuBinská et al. 2001). This study presents another 67 localities of this plant from the High and Western Tatra Mountains. In this massive, Pohlia ludwigii creates scanty-species phytocoenoses described as Pohlietum ludwigii (BalcerkiewicZ 1984, GórSki 2015, 2016). In the Tatra Mountains, Pohlia ludwigii has been found within the altitude range of 1,530–2,310 m a.s.l. In studies carried out between 2011 and 2013 by P. Górski, Pohlietum ludwigii phytoceonoses could be found during snow melts in June and the first half of July. 10. Riccardia latifrons (Lindb.) Lindb. Authors: H. klama, a. salacHna ATMOS Gd-33: S Poland, Beskid Żywiecko-Orawski Mts, Wielka Racza group (Grupa Wielkiej Raczy), Silesian Province, Żywiec County, Soblówka village, valley of Cichy potok stream, 49.42389°N, 19.13556°E, alt. 700 m a.s.l., on decaying wood of tree stump, leg., det. H. Klama, A. Salachna, 23.09.2011, ster. (herb. H. Klama). Riccardia latifrons is an epixylic liverwort found in lowland-mountain regions of Poland. In the mountains, R. latifrons grows on rotten wood in the forest lower belt. Riccardia latifrons is a very rare species in the Beskidy Zachodnie Mountains, and has been recorded in only a few instances in the Beskid Śląski Mountains (rejment-GrocHowska 1950), Beskid Żywiecko-Orawski Mountains (klama 1996), Gorce Mountains (mendelak 1977, mierZeńska 1994) and Beskid Sądecki Mountains (mamcZarZ 1977, mendelak 1977, sZweykowski & koźlicka 1980). The liverwort is also rarely found in the Tatra Mountains (sZweykowski & klama 2010, Górski & Váňa 2014). 11. Scorpidium scorpioides (Hedw.) Limpr. Author: P. Pawlikowski ATMOS Bf-34: NE Poland, Masurian Lake District, Ełk Lakeland (Pojezierze Ełckie), Warmia-Masuria Province, Ełk County, Stare Juchy, mire bordering Łaśmiady lake SW of the village of Sikory Juskie, 53.90281°N, 22.26146°E, large, topogenous, temporarily inundated extremely rich fen developed in the overgrown part of the lake, dominating and forming extensive carpets covering the area of over 3 hectares, along with Campylium stellatum, Limprichtia cossonii, Carex elata and C. lasiocarpa, not. P. Pawlikowski 2006-2016, leg., det. P. Pawlikowski, 09.2009 (WA). Scorpidium scorpioides is a prominent component of rich fen vegetation in the boreal zone of the Northern Hemisphere. Scorpidium scorpioides grows in temporarily or continuously inundated places within rich fens, including waterlogged carpets, small pools, and even shallow lake bottoms (ocHyra et al. 1988a). In Poland, S. scorpioides is considered endangered (category E, Żarnowiec et al. 2004). Scorpidium scorpioides has been recorded throughout the country, but is mainly aggregated in the post-glacial landscapes of northern Poland and in some upland areas (e.g., the Polesie region in eastern Poland) (ocHyra et al. 1988a). Scorpidium scorpioides is also found in north-eastern Poland, sometimes abundantly (locally in the East Suwałki Lakeland and Augustów Plain, e.g., jutrZen- New distributional data on bryophytes of Poland and Slovakia, 9 ka-trZeBiatowski & sZarejko 2001, Pawlikowski et al. 2009, Pawlikowski 2010a, sokołowski 2010). However, S. scorpioides has never been frequently recorded in the Warmia and Masuria Province (ocHyra et al. 1988a). Although S. scorpioides had been reported in the eastern part of this region (koppe & koppe 1931, BlocH et al. 1979), it is now rarely found there and its numbers are decreasing, with only a few recent published records (e.g., in “Jeziorko koło Drozdowa” nature reserve) (łacHacZ & olesiński 2000; P. Pawlikowski unpubl. 2012, 2016) and in the famous mire near the village of Zocie (BlocH-orłowska & Pisarek 2005; P. Pawlikowski unpubl. 2009, 2013). 12. Sphagnum fuscum (Schimp.) H. Klinggr. Author: P. Pawlikowski ATMOS Cd-97: Central Poland, Toruń-Eberswalde Urstromtal (Pradolina Toruńsko-Eberswaldzka), Płock Basin (Kotlina Płocka), Mazovia Province, Płock County, Płock commune, Gostynin-Włocławek Landscape Park, 'Jastrząbek' nature reserve, 52.50385°N, 19.60738°E, minerotrophic mire bordering SE part of the small, vanishing Jeziorko lake, single hummock in the Sphagnum-dominated fen with Betula pubescens tree stand, along with Sphagnum palustre, S. teres, Phragmites australis, Thelypteris palustris, Oxycoccus palustris and Carex acutiformis, leg., det. P. Pawlikowski, 6.08.2016 (WA). Sphagnum fuscum is a mountain-arctic-oceanicsubcontinental species and an important component of the moss layer of raised bogs, occurring also in some fens (dierssen 2001) and indicating habitat changes toward ombrotrophic conditions (ĆwiklinSka 2007). The rapid vanishing of S. fuscum from acidic mires in the region of Pomerania, where it used to be common, has been documented (jasnowski et al. 1968) and, generally, the species is decreasing in its southern lowland European range (dierssen 2001). Sphagnum fuscum is considered vulnerable in Poland (category V, Żarnowiec et al. 2004). Sphagnum fuscum has been recorded in the northern and western lowland areas of Poland, as well as in the mountains (sZaFran 1957), and remains only locally frequent in selected lakeland regions of the post-glacial landscapes of northern Poland (e.g., karcZmarZ & sokołowski 1985, HerBicHowa et al. 2007, Pawlikowski 2010b, P. Pawlikowski unpubl. 2003–2016) and submountain raised bogs of the Orawa-Nowy Targ Basin (kocZur 2007). In the predominating lowland landscapes of central Poland, where the newly discovered locality is situated, S. fuscum has rarely been recorded, with only two records to date in the Mazovia Province: one in the Torfowisko Serafin nature reserve (wąs 1960, P. Pawlikowski unpubl. 2013-2016) and one in the Zwoleńka river valley near the village of Stara Siekierka (jarZomBkowski & koZuB 2011). 37 13. Tomentypnum nitens (Hedw.) Loeske Author: P. Pawlikowski ATMOS Bf-12: NE Poland, Masurian Lake District, Warmia-Masuria Province, Giżycko County, Kruklanki commune, SE of the Borecka Forest, SW of the Możdżany village, 54.07287°N, 22.00658°E, small minerotrophic fen surrounded by agricultural land, desiccated due to intensive drainage by newly renovated drainage ditch, small hummock in a deteriorating sedge-moss vegetation overgrowing with trees and shrubs, along with Sphagnum teres and Calliergonella cuspidata, not. P. Pawlikowski, 10.08.2013. Tomentypnum nitens is considered vulnerable in Poland (category V, Żarnowiec et al. 2004) but remains relatively common in minerotrophic fens in some region, including some lakeland areas of northern and north-western Poland, the Biebrza area, uplands of southern Poland, and the Carpathians (ocHyra et al. 1988b). In the Warmia and Masuria Province, the T. nitens distribution is patchy and recent published records are rather limited (łacHacZ & olesiński 2000, łacHacZ & Pisarek 2002, 2007, BlocH-orłowska & piSarek 2005, Pawlikowski & jarZomBkowski 2010), although the species seems more numerous in the eastern part of the region (BlocH et al. 1979). It should be noted that many existing localities remain unpublished (M. Szczepański unpubl., W. Pisarek unpubl. from the years 1995–2016). In the Borecka Forest (a microregion within the Ełk Lakeland), the species was recorded only by koppe & koppe (1937, see ocHyra et al. 1988b) from two sites: (presently degraded) peatland between the village of Jabłonowo and Ciche lake, and peatland situated west of the northernmost part of Szwałk Wielki lake.
