Syntrichia latifolia (German Broad composite tooth moss ) is a moss -Art in the family pottiaceae . The species is often referred to as Tortula latifolia Bruch ex Hartm. called.
description
Syntrichia latifolia forms blue-green to blackish-green, loose lawns. The plants are about 1 to a maximum of 3 centimeters high. The leaves, which are piled at the tip of the stem and arranged in a rosette-like manner, are up to 3 millimeters long, folded when dry and curved inwards, spread out flat when damp, spatulate and broadly rounded. The leaf margins are slightly rolled back below and flat above. The strong vein ends in the tip or just before it.
The lamina cells are rectangular to elongated rectangular, smooth and hyaline at the base of the leaf, rounded-hexagonal in the upper half of the leaf, papillous and rich in chlorophyll on both sides. The back of the leaf vein bears one- to two-pointed papillae.
The gender distribution is diocesan . Spore capsules are very rare; they are erect, elongated cylindrical and straight or slightly curved. The yellow-red seta is up to 8 millimeters long. Peristome teeth are 1 millimeter long. The papillary spores are 10 to 15 micrometers in size.
Usually propagation takes place vegetatively through brood bodies , these are round, 24 to 36 micrometers in diameter, multicellular and can often be found on the inside of the upper half of the leaf.
Location requirements
The moss lives primarily in the floodplains of larger rivers in low-lying areas and populates here in particular the tree bark of willows and poplars in sunny to partially shaded places. More rarely, it grows on walls or sandstone. However, it does not tolerate prolonged flooding and requires high humidity in summer.
Frequent companion mosses are Leskea polycarpa , Bryoerythrophyllum recurvirostrum and Didymodon nicholsonii .
distribution
The species occurs in large parts of Europe, with the exception of areas north of southern Scandinavia and the continental east. In Central Europe, it is often found in the low-lying areas along the larger rivers. It can also be found in settlement areas at secondary locations. However, the species is completely absent at higher altitudes.
Further occurrences are in western North America.
