Pyrrhobryum Moss

Pyrrhobryum is a genus of mosses with several species found in various regions around the world. This entry provides information compiled from various sources regarding several species within this genus, including Pyrrhobryum spiniforme, Pyrrhobryum parramattense, and Pyrrhobryum mnioides.

Taxonomy and Nomenclature

  • Genus: Pyrrhobryum Mitt.
  • Family: Rhizogoniaceae
  • Class: Bryopsida
  • Order: Bryales
  • Kingdom: Plantae
  • Etymology: The name Pyrrhobryum comes from the Greek words "pyrros" (red) and "bryon" (a moss), likely referring to the reddish color of the peristome.
  • Taxonomic Serial Number (TSN): 547496 (for Pyrrhobryum), 548044 (for Pyrrhobryum spiniforme)

Selected Species:

  • Pyrrhobryum spiniforme (Hedw.) Mitt.
    • Common Name: pyrrhobryum moss
    • Synonyms: Hypnum spiniforme, Rhizogonium boninense, Rhizogonium pervilleanum, Rhizogonium spiniferum
  • Pyrrhobryum parramattense
    • Common Name: Parramatta Moss
  • Pyrrhobryum mnioides
  • Pyrrhobryum latifolium (Bosch &amp Sande Lac.) Mitt
  • Pyrrhobryum pungens (listed as the accepted name for Rhizogonium)

Distribution and Habitat

  • Pyrrhobryum spiniforme: Pantropical, found in Antarctica, Argentina, and Australia, among other locations.
  • Pyrrhobryum parramattense: Found in very moist situations in Australia, Norfolk Island, and New Zealand.

Morphological Characteristics and Growth Habits

  • Pyrrhobryum parramattense is described as a large and luxuriant moss.
  • Some species of Pyrrhobryum grow loosely on top of the soil and can be easily dislodged.
  • Stems have exterior cells in 2 or 3 layers.

Ecological Role

  • Pyrrhobryum mnioides can carpet forest floors in green moss, especially in wetter periods.

Genetic Information

  • Studies have used chloroplast loci (atpB-rbcL spacer, rps4 gene, and trnL intron and 3' spacer) to examine phylogeographic structure and cryptic speciation in Pyrrhobryum mnioides.

Interactions with Other Organisms

  • Pyrrhobryum spiniforme may grow epiphytically with other mosses such as a ciliate-toothed Plagiochila and various Lejeuneaceae.
