Taxiphyllum densifolium (Taxiphyllaceae) and other rare bryophytes of the Mecsek valleys (SW Hungary)
3-16Views:108In this paper, we deal with threatened and/or legally protected bryophytes found in the shady, forested valleys of the Mecsek Mountains, which are rare in national and/or local terms. Taxiphyllum densifolium, a rare moss in Europe has stable colonies with sporophytes in two valleys. This study is the first to describe the spore characteristics of this species. The previously considered unique and legally protected Rhynchostegiella teneriffae is nowadays so widespread in the Mecsek that it can no longer be considered a vulnerable species (VU) in Hungary. We present the first population of the legally protected Neckera pennata in Tolna county, and we also report on the recent, unusual occurrence of the data-deficient (DD) Fossombronia wondraczekii. We also list new populations of three other endangered (EN) species, Blindiadelphus recurvatus, Palustriella commutata and Porella arboris-vitae. Several vulnerable (VU) taxa such as Blepharostoma trichophyllum, Porella cordaeana, Sciuro-hypnum flotowianum, Seligeria pusilla, as well as new occurrences of near threatened (NT) mosses such as Microeurhynchium pumilum (with sporophytes), Phaeoceros carolinianus are documented. In addition, the data on Rhynchostegium rotundifolium in Jakab Mountain, which has not been recorded for more than 50 years, is confirmed. The difficulties of differentiating Hygroamblystegium species are briefly discussed.

Interesting moss and liverwort records from the Western Mecsek Mts (South Transdanubia, Hungary)
29-38Views:97During an extensive field work in the acidophilous forests and fens of the Western Mecsek Mts. current localities of several species, which haven’t been recognised here for 50 years, were revealed (e.g. Bazzania trilobata, Diphyscium foliosum, Scapania nemorea). The authors also found some new stands of regionally and/or locally rare taxa (e.g. Buxbaumia aphylla, Dicranum tauricum, Jamesoniella autumnalis, Lepidozia reptans, Sphagnum squarrosum) as well as species new to the moss flora of the Mecsek Mts. (e.g. Aulacomnium androgynum, A. palustre, Calliergon cordifolium, Hedwigia stellata). Both investigated habitat types were found to be infected by invasive moss (Campylopus introflexus) and liverwort (Riccia rhenana) species. It is noteworthy that most of the species were found in winter or at the beginning of spring, when most vascular plants are inactive and their coverage is negligible. In this period moss and liverwort taxa are active, and are therefore easily noticeable. The authors raise the possibility that the expansion of Dicranum tauricum in Hungary is a consequence of former coniferous (especially Pinus spp.) plantations, since the old, dead trunks of pine species can serve as stepping stones to colonization for this taxon.

New montane species in the Hungarian bryophyte flora
16-26Views:664During a bryofloristical investigation in the vicinity of Ómassa (Miskolc) in the Bükk Mountains (NE Hungary), three montane-boreal bryophyte species new to the Hungarian bryoflora were collected. Encalypta spathulata Müll.Hal. was found on the ledges of limestone cliffs of Vörös-kő Hill as well as on the rocky debris among roots of a fallen tree lying under the cliffs. Hydrogonium croceum (Brid.) Jan Kučera and Orthothecium rufescens (Dicks. ex Brid.) Schimp. were found in the crevices of dolomite cliffs on the north-facing steep slope of Jávor Hill. While the latter two species are widespread in European Mountains, E. spathulata is considered to be a rare species, and is assessed as ‘Vulnerable’ in the IUCN red list.

Bryophyte flora of the Arboretum of Szarvas (Hungary, Békés county)
140–152Views:390In this study we present the current moss and liverwort flora of the Arboretum of Szarvas. The observations were made in 2017, 2019, 2020 and 2021. Altogether 95 bryophyte taxa (7 liverworts and 88 mosses) were identified. Most of them are considered to be common in Hungary, however some species are rare in the Great Hungarian Plain: Lophocolea coadunata, Climacium dendroides, Hylocomiadelphus triquetrus, Pleurozium schreberi, Polytrichum formosum, Rhytidiadelphus squarrosus, Ulota crispula, Zygodon rupestris. These results also confirm the conservational and scientific value of the arboretum.

Bruchia flexuosa (Schwägr.) Müll. Hal. a true peculiarity in the Hungarian bryoflora
193-201Views:128The fifth European occurrence of the moss species Bruchia flexuosa possessing a holarctic distribution range with a North American centre was encountered in Hungary. Outside of the North American continent only two Asian (both from Japan) and four European occurrences from four different countries (Italy, Austria, Slovenia, Croatia) have hitherto been reported. Apart from the recent Japan findings and the Croatian record observed in 1987, all other European records date back to the 19th century. Our paper reports the circumstances of the Hungarian occurrence along with a short descriptions and photographic illustrations of both the species and its habitat.
