The pointed-leaved fair-billed moss ( Eurhynchium striatum ) is a pleurocarpes deciduous moss from the Brachytheciaceae family .
features
This type of moss forms loose, green, shiny and often quite extensive lawns up to 5 centimeters high. The strong plants are often branched like trees, individual branches are often extended like a flagella. Stem leaves are 2 millimeters long, protruding sparsely, narrowed to a sharp point from a broad, egg-shaped base, longitudinally folded, with flat or narrowly rolled edges all around and sawn around. The leaves are about 1.3 to 2 times as long as they are wide and the leaf edges at the tip of the leaf are at an angle of 15 to 45 degrees. Branch leaves are somewhat smaller and narrower, about 1.5 to 1.8 millimeters long, ovoid and gradually pointed. All leaves have a simple rib up to about 3/4 of the leaf length, with the end of the rib usually emerging as a thorn on the back of the leaf. The leaf cells are linear and thin-walled in the middle of the leaf, shorter at the base of the leaf, somewhat wider, moderately thick-walled and spotted; the leaf wing cells are rectangular.
The moss is diocesan and has a moderate fruiting rate, with spore ripening spread over the whole year, but mainly in the winter half-year. The sporophyte has a red, smooth seta , which becomes about 2.5 centimeters long and carries a sloping to horizontal, curved, cylindrical spore capsule. The spores are finely granulated and 11 to 14 µm in size.
Occurrence and distribution
The pointed-leaved fair-billed moss grows in shady, fresh or moist, alkaline locations mainly on the forest floor of nutrient-rich deciduous forests, also on rotten wood, on stem bases as well as on stones and walls.
In Central Europe it is common and widespread from the plains to the lower mountain forests. The total distribution includes Europe, Asia and North Africa.
Similar closely related species
The pointed-leaved fair-billed moss resembles the closely related stump-leaved fair- billed moss ( Eurhynchium angustirete ), which is seldom found in the plains and mainly in the montane altitudes. The pointed-leaved fair-billed moss differs from that species by the longer and narrower, pointed stem leaves.
