Rimmed Lichen

The term "rimmed lichen" refers to a variety of lichens, not a single species, characterized by a distinct rim or edge on their thallus or apothecia. This page explores several lichens that fall under this general description.

Considerations for Pets

  • Some resources mention the use of wirework cloches to protect plants from animals like deer, rabbits, squirrels, and birds. These cloches, sometimes copper-rimmed, may present a physical barrier that pets could interact with.

Scientific Names and Synonyms

  • Several species are identified as "rimmed lichen":
    • Aspicilia reptans (Rimmed Lichen)
      • Synonyms: Lecanora reptans, Lecanora ryrkaipiae
    • Aspicilia calcarea (Calcareous Rimmed Lichen)
    • Aspicilia annulata (Rimmed Lichen)
    • Lecanactis salicina (Old Wood Rimmed Lichen)

Taxonomy and Nomenclature

  • Family: Hymeneliaceae (for Aspicilia species)
  • Family: Roccellaceae (for Lecanactis salicina, old wood rimmed lichen)
  • Symbol: ASPIC2 (for Aspicilia)
  • Kingdom: Fungi (lichens are a symbiotic relationship between a fungus and algae)

Distribution and Habitat

  • Aspicilia calcarea (Calcareous Rimmed Lichen) can be found on limestone rock, such as in the valley of the Dry Frio River and Olonne-sur-Mer, Vendee, Pays de la Loire, France.
  • Other rimmed lichens are found in various regions, including Ireland, California (Sagehen Creek Basin), and France (Pyrenees, Western France).

Morphological Characteristics

  • Lichens generally consist of a fungus and either a green algae or a blue-green algae, or a combination of both.
  • Crustose lichens often have a distinct rim surrounding their cup-shaped apothecia.

Ecological Role

  • Lichens are a symbiosis of fungi and algae.

Interactions with Other Organisms

  • Lichens can be associated with copper mineralization.
  • Wirework cloches are used to protect plants from animals like deer, rabbits, squirrels, and birds.
