Broom Forkmoss (Dicranum scoparium)

Dicranum scoparium, commonly known as broom forkmoss or mood moss, is a widely distributed species of moss appreciated for its distinctive appearance and ecological role.

Considerations for Pets

  • Snails tend to avoid mosses, potentially due to the presence of oxylipins.

Taxonomy and Nomenclature

  • Scientific Name: Dicranum scoparium Hedw.
  • Common Names: Broom forkmoss, Mood Moss, Broom Moss, Wind-blown moss, Fork moss
  • Family: Dicranaceae
  • Synonyms: Mentions of Orthodicranum fulvum, Dicranum fulvum, Dicranum polysetum, Dicranum fuscescens, Dicranum bonjeanii, Dicranum congestum, Dicranum viride, Dicranum majus, and Dicranum gregoryi suggest these may be closely related species within the Dicranum genus, or possibly synonyms.

Distribution and Habitat

  • Native to North America, including the Great Lakes region, Alaska, and California.
  • Also found in Europe (Dicranum viride).
  • Prefers acid soils or rock substrates and thrives best in shady locations.
  • Grows atop rocks ("Rock Cap Moss") and on boulders in woods.

Morphological Characteristics and Growth Habits

  • Can reach up to 10 cm in height.
  • Forms yellow-green or dark green cushions or large patches.
  • Leaves are 4 to 7.5 mm long and narrowly shaped.
  • Robust, densely tufted cushion moss with long narrow leaves that grow asymmetrically, resembling bent swords.

Quirky Facts

  • The appearance of Dicranum scoparium changes with moisture levels; it appears wispy and irregular when dry but becomes more vibrant when moist, hence the name "Mood Moss".
  • Leaves grow asymmetrically like bent swords.

Interactions with Other Organisms

  • Snails tend to avoid mosses, possibly due to the presence of oxylipins, which spoil their appetite.
