Plagiomnium

Familie: Mniaceae(de) Ordnung: Bryales(de)

Within the family the plants of this genus are characterized by their prostrate or erect, but pendant habit. Only fertile plants are completely erect, with a tuft of leaves at the tip, or rosulately ramified.

The leaves are big and limbate (bordered by elongate cells). The edge of the leaves is serrate.

Plagiomnium undulatum (Hedw.) T.Kop.

Within the genus this species is simply recognizable by its long lingulate, often 1cm long, and clearly undulate leaves.

It is a really common european and asian species. It grows at all humid locations, e.g. near brooks or beside forest paths. In most cases it is erect and pendant, and it can be as high as 10cm. Alone by its size and its fresh light green color the plant is rather noticeable.
