This document presents new sites of two invasive moss species; Campylopus introflexus and Orthodontium lineare. These species had previously been found on only three sites near Łódź. Two new sites have been identified in the city of Łódź.
The paper presents socio-ecological and ecological characterisation of 72 bryophyte species found in the years 2008-2012 on midforest roads passing through nine nature reserves situated in the Łódź region. Nine species occurred excl usively in this habitat. Most of the species noted (63%) were forest bryophytes occurring also inside the forest phytocoenoses studied, they constituted 95.5% of all the records. The non-forest species show diff erent socio-ecological relations: some of them occur typically on meadows or in grassy forest ecotones, others – in fens or bogs but there are also some pioneer bryophytes colonizing initial sites, both of natural and anthropogenic character. They diff er from the forest species occurring on midforest roads in their ecological demands regarding the habitat reaction (presence of subneutral species) and light (higher participation of heliophytes). Nine of them (13%) are considered to be synanthropic bryophytes. Details of the species occurrence are provided.
Błotniszek wełnisty Helodium blandowii (F.Weber & D.Mohr) – mech charakterystyczny dla siedlisk oligotroficznych, uznany w Polsce za relikt glacjalny i objęty ochroną ścisłą – dotychczas odnotowany na dwóch stanowiskach w Polsce Środkowej. Niniejsza notatka prezentuje dwa dalsze stanowiska z tego obszaru – na torfowiskach niskich w Kolonii Grabostów, w dolinie rzeki Pilsi (dopływ Widawki), w gminie Zelów i w Bęczkowicach, w dolinie Luciąży (gmina Łęki Szlacheckie, woj. łódzkie)
Field investigations into slime moulds were conducted in the “Bory Tucholskie” National Park in 2014. These were preliminary inventory studies, as research into myxogastria had not been conducted previously in this area. A total of 34 taxa (32 species, 2 varieties) belonging to 16 genera were identified. Of them, Stemonitopsis amoena (Nann.-Bremek.) Nann.-Bremek. is a species new to the biota of Poland. The taxon Symphytocarpus flaccidus is on the red list of slime mould rare in Poland. Localities of two species – Cribraria languescens Rex and C. pertenuis Flatau & Schirmer, were recorded in Poland for the second time.
New distribution data for 171 bryophyte taxa in the Roztocze National Park are provided. Among them there are 43 species protected by law in Poland, including 20 strictly protected species, as well as 13 species threatened in Poland. The research revealed 36 species (5 liverworts and 31 mosses) new for the region. Noteworthy is the occurrence of 19 mountain species and 10 bryophytes thought to be relicts of old-growth forests what confirms the specificity of nature of the Roztocze region. The most valuable and interesting finds are: mosses Campylophyllopsis sommerfeltii (Myrin) Ochyra, Dicranum viride (Sull. & Lesq.) Lindb., Buxbaumia viridis (Moug. ex Lam. & DC.) Brid. ex Moug. & Nestl. as well as liverworts Calypogeia suecica (Arnell et J. Perss.) Müll. Frib. and Cephalozia catenulata (Huebener) Lindb. A brief characterisations of these species are presented.
New distribution data for 183 species, one subspecies and four varieties of bryophytes in the Świętokrzyski National Park are provided. The most interesting species (rare, protected and new for the area) are Anastrophyllum hellerianum, Buxbaumia viridis, Cephalozia catenulata, Dicranum viride, Lophozia ascendens, Mannia fragrans and Tetraplodon angustatus.
