  Based on data collected during field surveys between 2012–2014, the author presents the results of bryofloristical studies carried out in an abandoned alumina refinery. The author has detected altogether 46 bryophytes from the territory, of which 15 species are new to the bryoflora of the settlement. In the surroundings of the industrial zone (where alumina production was carried out until 1997) some bryophytes, which are classified as least concern (Brachythecium albicans, Brachythecium tommasinii, Rhynchostegium murale) and near threatened status in the Hungarian Red List (Aloina aloides, Brachythecium glareosum, Dicranella staphylina, Didymodon insulanus, Orthotrichum pumilum), can be found.

  In 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.
