Dicranum flagellare ( whip-fork-tooth moss ) is a deciduous moss - species from the family Dicranaceae . A frequently used synonym is Orthodicranum flagellare (Hedw.) Loeske .
features
The moss forms moderately dense, lively green to yellow-green lawns, which are particularly often littered in late summer and autumn with the needle-shaped, yellowish, approximately 3 millimeter high brood shoots typical of this species. In this phase it is almost unmistakable and easy to recognize in the terrain.
The plants, up to 5 centimeters in size, are usually densely rhizoid-felted. The leaves, which are slightly one-sided, are narrowly lanceolate and end in a tubular awl tip, only serrated at the tip, otherwise with entire margins. The rib takes up about a third of the leaf width at the leaf base and extends into the leaf tip or ends just before it. The lamina cells are square to slightly rectangular above, smooth, not or barely spotted, elongated at the base of the leaf. Spore capsules are very rarely formed.
Distribution and location requirements
Dicranum flagellare occurs in Europe, parts of Asia and from North America to northwestern South America. In Central Europe, the moss is only moderately frequent or rare. It avoids lime and grows from low-lying to middle-mountain areas in humid and humid forests, mainly on bark and rotten wood.
