Bryum is a large and diverse genus of mosses belonging to the family Bryaceae. The genus encompasses over a thousand described species, although some have been reclassified into segregate genera.
Taxonomy and Nomenclature
- Genus: Bryum
- Family: Bryaceae
- Kingdom: (Implied, likely Plantae)
Some species and synonyms include:
- Bryum dixonii Cardot ex W.E.Nicholson (Dixon's Thread-moss)
- Bryum capillare
- Bryum argenteum Hedw. (Silvergreen Bryum Moss)
- Bryum miniatum Lesq. (Red Thread-moss, Glossy Red Bryum Moss)
- Bryum muehlenbeckii (Muehlenbeck's Bryum Moss)
- Bryum dichotomum (also known as Bryum bicolor)
- Rosulabryum capillare
- Bryum algovicum var. algovicum Sendtn. ex C. Mll.
- Bryum aeneum Blytt ex Bruch & Schimp. in B.S.G.
- Rhodobryum roseum (formerly Bryum roseum)
Distribution and Habitat
- Bryum dixonii is endemic to Scotland and occupies montane habitats.
- Bryum capillare was observed at bluff overlooking Alum Creek in Delaware Ohio.
- Bryum argenteum is found in the Gurbantunggut desert as an important component of the Biological Soil Crusts (BSCs).
- Baltic bryum is found on grazed salt marshes in the Netherlands.
- Rhodobryum roseum is found throughout most of the world in woods or sheltered grassy areas.
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. It grows in tufts or patches, with stems mostly 1 to 3 cm tall. Dry plants usually have corkscrew-like shoots, with leaves spirally twisted around the stem.
- Long-leaved thread moss grows in tufts, is reddish-green in color, and has leaves that are rather long.
- Other Bryum species are erect in green to brownish-green tufts or turfs, to 1.5 cm high.
- Bryum flaccidum grows with its leaves arranged in a rosulate pattern.
Ecological Role
- Bryum argenteum is an important component of Biological Soil Crusts (BSCs).
Interactions with Other Organisms
- Waitea circinata is an important fungal pathogen of amenity turfgrasses and is especially associated with Bryum argenteum.
Genetic Information
- RAPD (Random Amplified Polymorphic DNA) technique has been used to assess the level of genetic diversity in Bryum pseudotriquetrum.
