Hygrobiella laxifolia (Hook.) Spruce – eine neue Lebermoosart für die Tschechische Republik

Hygrobiella laxifolia (Hook.) Spruce was recorded for the first time in the Czech Republic. The three new occurrences lie in two valleys of the National Park Bohemian Switzerland (České Švýcarsko) and the adjacent Protected Landscape Area Labské pískovce and extend thus the known distribution area in the Saxonian part of the Elbe Sandstones. All records were made on sandstone boulders in periodically dried-up streams.
