The wave-leaved Katharinenmoos or bald hat moss ( Atrichum undulatum ) forms loose, dark green lawns up to ten centimeters high.
Its rungs are connected underground and easily detachable. The stems are erect, not branched and leafy all around.
The leaves are five to ten millimeters long, tongue-shaped, lanceolate and wavy across, the underside is toothed. The leaf margin is roughly double serrated and hemmed. The rib on the upper side of the leaf has upright fins.
Ecology and diffusion
The wave-leaved Katharinenmoos occurs on shady, humus-rich, more or less moist, loamy soils , such as on slopes in deciduous forests. It is widespread in Europe except in the northern areas. It is also found in North America and Asia, as well as in Algeria and the Azores.
Similar species
Similar species are the gooseneck star moss ( Mnium hornum ), but without lamellae on the rib and Plagiomnium undulatum . The tip of the leaf is rounded and the underside of the leaf is smooth.
Naming
In 1780 the German pharmacist and botanist Jakob Friedrich Ehrhart named this moss after the Russian Tsarina Katharina the Great . The scientific generic name is derived from the Greek word ἄθριξ (Greek athrix, hairless). The specific epithet comes from the Latin word 'unda' - the wave.
