Mechorosty zaznamenané během 35. podzimního setkání Bryologicko-lichenologické sekce ČBS v Jizerských horách

Altogether 227 taxa of bryophytes (59 liverworts and 168 mosses) were recorded at excursions in the Jizerské hory Mountains in North Bohemia. The most interesting records include the moss Timmia austriaca, which had so far only been known from a single locality in the valley of the Jizera river c. 20 km downstream, and of the Critically Endangered liverwort Cladopodiella francisci at Klugeho louka mire of the mire complex near the Jizerka settlement. Six other species (liverworts Cladopodiella fluitans, Marsupella sprucei, Odontoschisma sphagni, and Scapania cuspiduligera, mosses Anoectangium aestivum and Warnstorfia pseudostraminea) are considered Endangered, Cephaloziella spinigera is listed as Vulnerable, and five species (Frullania tamarisci, Porella cordaeana, Solenostoma hyalinum, Sphagnum fuscum, and Splachnum sphaericum) are classified as Near Threatened. Calypogeia fissa var. paludosa, Marsupella subemarginata, and Sphagnum medium are recently segregated species whose distribution is insufficiently known but which are obviously uncommon, and the same is true for the rare Central European endemic species, Sciuro-hypnum flotowianum (Data Deficient). Dicranum fuscescens has so far been regarded to be relatively common, but the revision of its specimens has confirmed it to be a very rare species in the region, known with certainty from only two localities in the Czech Republic so far.
