Pyrrhobryum Moss: A Detailed Overview

Pyrrhobryum is a genus of mosses belonging to the family Rhizogoniaceae. This overview consolidates information about several species within the genus, including Pyrrhobryum spiniforme, Pyrrhobryum mnioides, and Pyrrhobryum parramattense.

Taxonomy and Nomenclature

  • Genus: Pyrrhobryum Mitt.
  • Family: Rhizogoniaceae
  • Class: Bryopsida
  • Order: Bryales
  • Kingdom: Plantae
  • Notable Species:
    • Pyrrhobryum spiniforme (Hedw.) Mitt. (Common Name: Pyrrhobryum Moss)
    • Pyrrhobryum mnioides
    • Pyrrhobryum parramattense
  • Synonyms: Rhizogonium spiniforme (Hedw.) Bruch in Kraus.
  • Alternative name: Umbrella Thyme-moss (for an unknown species)

Distribution and Habitat

  • Pyrrhobryum parramattense is found in very moist situations in Australia, Norfolk Island, and New Zealand.
  • Pyrrhobryum spiniforme is found in Antarctica, Argentina, and Australia.
  • Pyrrhobryum mnioides is a trans-Antarctic moss.

Morphological Characteristics

  • Plants are described as green to olive green, large, and rigid, growing in tufts.
  • Stems can reach 7-9 cm in length, are scarcely branched, and have abundant rhizoids on the lower third of the stem.
  • Densely foliate
  • Pyrrhobryum gets its name from the Greek pyrros (red) and bryon (a moss), presumably in reference to the reddish color of the peristome.

Quirky Facts

  • One text excerpt questions moss lying "fairly loosely on top of the soil and is very easily dislodged."

Genetic Information

  • Chloroplast loci (atpB-rbcL spacer, rps4 gene, and trnL intron and 3' spacer) have been used to study the phylogeographic structure and cryptic speciation in Pyrrhobryum mnioides.
