Rimmed Lichen: A Diverse Group of Lichens

The term "rimmed lichen" refers to several lichen species across different genera. This article explores various lichens referred to as "rimmed lichens," highlighting their scientific classifications, habitats, and interesting characteristics.

Considerations for Pets

  • Some "rimmed lichens" grow on wood and rock surfaces, potentially within reach of pets in outdoor environments.

Scientific Names and Common Names

  • Rimmed Lichen: This common name applies to multiple lichen species.
  • Aspicilia reptans: One species known as Rimmed Lichen.
  • Aspicilia calcarea: Also known as Calcareous Rimmed Lichen.
  • Lecanactis salicina: Also known as old wood rimmed lichen.

Taxonomy and Nomenclature

  • Family: Hymeneliaceae (for Aspicilia species) and Roccellaceae (for Lecanactis species). Megasporaceae for at least one Calcareous Rimmed Lichen record.
  • Group: Lichen
  • Synonyms/Alternative Names:
    • Lecanora reptans (synonym for Aspicilia reptans)
    • Lecanora ryrkaipiae (synonym for Aspicilia reptans)

Distribution and Habitat

  • Calcareous Rimmed Lichen (Aspicilia calcarea) is found on limestone rock.
  • Sagehen Creek Basin, CA
  • Dry Frio River valley
  • Olonne-sur-Mer, Vendee, Pays de la Loire, France
  • Aspicilia reptans is not found in Idaho.

Morphological Characteristics

  • Crustose lichens have apothecia with a rim surrounding the cup-shaped structure.

Interactions with Other Organisms

  • Lichens are a symbiotic relationship between a fungus (mycobiont) and algae (photobiont). In the case of old wood rimmed lichen (Lecanactis salicina) the photobiont is in the Roccellaceae family.
