Contributions to the bryophyte flora of the Alcsík Basin, Romania

Abstract

A recent investigation on the bryophyte fl ora of the Alcsik Basin resulted in recording 70 bryophyte taxa (5 liverworts and 65 mosses). Although declining in some aspects, the area still preserves very valuable bryophyte vegetation rich in elements characteristic for fens and mires. Hamatocaulis vernicosus is the most valuable species recorded, a bryophyte included in the Bern Convention, in the European Union Habitats and Species Directive, and in the Red data book of European bryophytes. Several other rarities in SE Europe occur in the investigated area, including Breidleria pratensis, Dicranum bonjeanii, Drepanocladus polygamus, Philonotis marchica, P. caespitosa, Plagiomnium ellipticum, Polytrichum strictum, Scorpidium cossonii, Sphagnum spp., and Tomentypnum nitens. Some of these, such as Plagiomnium ellipticum or Tomentypnum nitens, are very abundant and represent the largest populations recently recorded in SE Europe.
