Interesting records of bryophytes from Silesia Province (Poland)
Distributional data for 22 rare bryophytes from Silesia Province are provided. The most interesting plants include Acaulon muticum (Hedw.) Müll. Hall., Helodium blandowii (F. Weber & D. Mohr) Warnst., Hygroamblystegium tenax (Hedw.) Jenn. and Orthotrichum patens Brid.
Philonotis calcarea (Bruch & Schimp.) Schimp. in Poland is a montane species, very rarely occurring in lowland, strictly protected by law. In the Opole Province till this time it has been known from four localities, reported from the 19th and first half of the 20th century. The paper presents description of the new locality and list of stations of P. calcarea in the Opole Province. Current distribution of this species is presented on the map.
The paper presents the contribution to the bryoflora of the Vistula Spit, a bryologically poorly known region located in northern Poland. As a result, localities of 59 species and 2 varieties of bryophytes were found, including regionally rare, interesting and protected in Poland bryophytes, such as Aulacomnium androgynum (Hedw.) Schwägr., Orthodontium lineare Schwägr., Orthodicranum tauricum (Sapjegin) Smirnova, Rhodobryum roseum (Hedw.) Limpr. and Ulota crispa (Hedw.) Brid.
Preliminary studies on the bryoflora of the Narwiański National Park located in northeastern Poland were carried out in July 2011. As a result, localities of 82 species (6 liverworts and 76 mosses) were discovered. The most interesting are Aulacomnium androgynum (Hedw.) Schwägr., Hedwigia ciliata (Hedw.) P.Beauv., Leptodictyum humile (P.Beauv.) Ochyra, Plagiothecium latebricola (Wils.) Schimp., Syntrichia papillosa (Jur.) Wilson and S. virescens (De Not.) Ochyra.
The paper presents the preliminary results of using the herbarium specimens of selected mosses (Brachythecium rutabulum (Hedw.) Schimp., B. salebrosum (F.Weber & D.Mohr) Schimp. and Hypnum cupressiforme Hedw, for assessment of changes in the heavy metals pollution in Katowice town. For the initial studies lead and cadmium have been chosen, which are among the most toxic heavy metals. Specimens originate from two periods: the nineties of 20th century and from 2012. To verify the correctness of assumption the control samples were selected from the collection of mosses from the Białowieża Primeval Forest considered as a “clean” part of Poland, in the nineties of 20th century, stored in the same conditions. The results obtained in these investigations confirm the possibility of application of herbarium specimens of mosses in the biological assessment of changes in lead and cadmium contamination.
The paper presents information about habitat conditions of occurrence of the Ptychoverpa bohemica (Krombh.) Boud. fungus in man-made habitats in Silesian Upland in southern Poland. Soil samples were collected from 5 sites in order to measure the contents of organic carbon, nitrogen, carbon/nitrogen ratio and percentage of organic matter, as well as the values of pH and electric conductivity. Lists of plants associated with Ptychoverpa bohemica were also prepared. Results of the investigation show that pH values of analysed soils are neutral to slightly acidic, they show negligible salinity, and the content of organic carbon, nitrogen and organic matter are higher in their upper levels. The floristic composition of patches with Ptychoverpa bohemica usually consists of species which are common in urban areas, such as apophytes and anthropophytes, for example: Betula pendula, Brachythecium rutabulum, Epipactis helleborine, Pinus sylvestris, Populus tremula, Quercus robur, Salix caprea and Sorbus aucuparia.
The paper provides information about new localities of 118 species, including 2 hornworts, 22 liverworts and 94 mosses collected at the Ciężkowickie Foothills. The most interesting are bryophytes protected and threatened in Poland, for example Fossombronia wondraczekii, Nowellia curvifolia, Sphagnum compactum, Trichocolea tomentella and Weissia squarrosa.
This paper presents current distribution of the moss Diphyscium foliosum (Hedw.) D.Mohr in the Polish part of the Carpathians. Till this time, the species has been known from the 139 localities distributed through the whole territory, but with their distinct concentration in the Western Beskidy Mountains. The altitudinal limits, habitat preferences and its threats are briefly provided. Eighteen localities, mainly from Beskid Śląski and Beskid Sądecki ranges are reported for the first time.
