Calliergon (German Schönmoose ) is a genus of deciduous mosses in the order Hypnales .
features
Calliergon species are mostly strong, almost unbranched to almost feathery, upright or ascending plants that grow in extensive lawns or individually between other mosses. The stem leaves are more or less protruding or adjoining roof tiles, hollow, circular or heart-shaped to eilanzettlich, the tip of the leaf hood-shaped, rounded, sometimes with a small point. The leaf margins are whole and flat. The simple leaf vein extends to the middle of the leaf or above. Branch leaves are smaller and narrower than the stem leaves. The lamina cells are linear-worm-shaped in the middle of the leaf, shorter in the tip of the leaf, wider and rectangular at the base of the leaf, thick-walled and pitted. The leaf wing cells are usually thin-walled, hyaline, inflated and sharply demarcated from the other cells, rarely thick-walled and less well demarcated.
The species are dioecious or autocratic (antheridia and archegonia on different branches on the same plant). The seta is very long and meandering, the spore capsule inclined to horizontal and curved, the capsule lid is obtuse or conical.
Location requirements
The mosses usually grow in wet or damp places in swamps and moors.
