The Bryaceae or Birnmoosgewächse are a cosmopolitan moss - family . They get their German name from their pear-shaped capsule, which is never upright, but always hanging or nodding.
features
The stems are mostly upright. The leaves are ovate to ovate-lanceolate. The rib is short and ends before the tip of the leaf. The cells of the leaf blade have a somewhat elongated, hexagonal shape or are elongated (prosenchymatous). However, they are almost never as plump as in the closely related family Mniaceae .
The capsule is ovate to cylindrical, has a neck and is usually inclined or nodding. The peristome is double.
Occurrence
The family is spread around the world. Most species grow predominantly on soil, less often on rock or bark. They are particularly common in open pioneer and disturbed locations, therefore often in an environment characterized by people.
Systematics
The Bryaceae comprise 10 genera with around 660 species. The genera are:
- Acidodontium
- Anomobryum , also in Central Europe
- Brachymenium
- Bryum (pear moss), also in Central Europe
- Haplodontium
- Imbibryum
- Mielichhoferia , especially on rocks containing heavy metals
- Perssonia
- Rhodobryum , also in Central Europe
