Abstract: The liverwort Schistochilopsis opacifolia, considered vanished from the Czech bryoflora, was detected in recent collections from the Labská rokle ravine in the Krkonoše Mts, and its identification and distinctness from S. incisa was confirmed by molecular barcoding using trnL–trnF chloroplast sequences. A selective partial revision of material collected in the summit region of the Krkonoše Mts yielded several other specimens, all of which were collected in the Labský důl valley. The diagnostic characters of the species are discussed to prompt the search for other localities of this rare, yet probably partly overlooked, species of our liverwort flora.
