Neckera pennata (Feathered Neckermoss) is a deciduous moss species from the Neckeraceae family .
description
The species forms gray-green to yellow-green, shiny lawns, similar to Neckera crispa , with mostly up to 5 (maximum 10) centimeters long stems. These are usually pendulous with upturned tips, irregularly pinnate and flattened with leaves. Flagella (thin, small-leaved branches) are rare. The transversely wavy, egg-shaped elongated leaves are pointed short, the leaf margin at the base is curved on one side, otherwise flat and serrated in the upper part. A vein is missing or short and forked.
The leaf cells in the middle of the leaf are linear, 5 to 8 µm wide and thick-walled, rhombic extended towards the leaf tip, rounded in the leaf corners.
The moss is monözisch and almost regularly forms numerous spore capsules. These are elongated egg-shaped, have a very short, up to 1 millimeter long seta , so they are almost sitting and are surmounted by the perichetial leaves. The cone-shaped capsule lid has a short beak. The spores are papillary and 15 to 25 µm in size.
distribution
Neckera pennata occurs in Europe, parts of Asia, America, tropical Africa as well as Australia and New Zealand. Although the species is widespread in Central Europe, it is often rare or even extinct in some areas. It is very sensitive to air pollution.
Location requirements
The moss usually grows on the bark of deciduous trees in shady and humid forests of the montane altitude level up to about 1000 meters above sea level.
