Brachythecium Moss

The genus Brachythecium encompasses a variety of mosses, commonly referred to as brachythecium moss or feather-moss. Several species and forms are mentioned, including Rough-stalked Feather-moss (Brachythecium rutabulum), Velvet Feather-moss (Brachythecium velutinum), Stiff Brachythecium Moss (Brachythecium turgidum), Acuminate Brachythecium Moss (Brachythecium acuminatum), and Whitish Feather-moss (Brachythecium albicans).

Considerations for Pets

  • Some varieties form "shag carpet moss," which can be soft and fluffy. This might be attractive to pets, so monitor for ingestion.

Taxonomy and Nomenclature

  • Family: Brachytheciaceae
  • Genus: Brachythecium Schimp. in B.S.G.
  • Synonyms/Alternative Names:
    • Brachytheciastrum velutinum (for Brachythecium velutinum)
  • Varieties:
    • Brachythecium reflexum var. reflexum (Starke in Web. &amp Mohr) Schimp. in B.S.G.
    • Brachythecium albicans var. occidentale

Distribution and Habitat

  • Brachythecium is described as a difficult genus in California.
  • Generally, species prefer mesic (moderately moist) sites, but not inundated ones. Brachythecium frigidum is noted as an exception.
  • Brachythecium salebrosum is described as a forest creeping moss.
  • Several species are found in specific habitats:
    • Brachythecium albicans: Widely distributed on dune ridges.
    • Brachythecium rivulare: Found on rocks in and beside streams.

Morphological Characteristics

  • Brachythecium mosses are variable in form, often forming loose, medium-sized patches.
  • Capsules (spore-containing structures) are frequently observed, having a curved, egg-shaped form with a roughened seta (stalk).
  • Brachythecium salebrosum is noted as being medium-sized to large.

Ecological Role

  • Bryum algovicum (Drooping Thread-moss) and Brachythecium albicans are mentioned as pioneer species.

Quirky Facts

  • One person refers to a form of Brachythecium as "Star moss" due to its appearance and soft texture, and uses it in terrariums.
  • One source humorously notes "brachythecium moss. is flaky way, with few cookies petting the vehicle at service and manual. just, brachythecium moss step-by-step prevents between biryani." This appears to be nonsensical text but suggests the name is being used in unusual contexts online.

Interactions with Other Organisms

  • The text mentions heavy metal-induced physiological alterations and oxidative stress in Brachythecium piligerum, indicating its use in studies related to environmental pollution.

Further Information

  • TSN (ITIS Taxonomic Serial Number) 16242 is provided for Brachythecium velutinum.
  • ARKive is mentioned as a source of information and photos for "Mrs. Appleyard's moss."
  • The Toolik-Arctic Geobotanical Atlas maps contain information on Brachythecium moss.
