Distribution and Habitat
- Bryum dixonii is endemic to Scotland, occupying montane habitats.
- Bryum argenteum has a cosmopolitan distribution.
- Rhodobryum roseum (formerly Bryum roseum) is found throughout most of the world in woods or sheltered grassy areas.
- Baltic bryum grows on grazed salt marshes in the Netherlands.
- Bryum capillare was observed at bluff overlooking Alum Creek in Delaware Ohio.
- Bryum caespiticium was observed at Greenville Falls State Naure Preserve, Miami County, Ohio.
Morphological Characteristics and Growth Habits
- Bryum capillare grows in tufts or patches, with stems.
- Bryum argenteum forms pale green or almost white, compact tufts or patches that look shiny and silvery grey.
- Stems are mostly 1 to 3 cm tall.
- Dry plants of some species usually have corkscrew-like shoots, with leaves spirally twisted around the stem.
- Bryum argenteum forms very close tufts or cushions; it occurs in patches or is found as scattered individuals mixed with other mosses.
- Some species grow in tufts and are reddish-green in color.
- Bryum caespiticium forms crowded clumps of leaves at the upper ends of the stems.
- Bryum flaccidum grows with its leaves arranged in a rosulate fashion.
Ecological Role
- Bryum argenteum is an important component of the Biological Soil Crusts (BSCs) found in the Gurbantunggut desert.
Genetic Information
- The RAPD (Random Amplified Polymorphic DNA) technique has been used to assess the level of genetic diversity in Bryum pseudotriquetrum.
Interactions with Other Organisms
- Bryum argenteum exhibits dependence on epiphytic bacteria for freezing protection in Antarctic environments.
- Waitea circinata is an important fungal pathogen that affects Bryum argenteum on amenity turfgrasses.
