Rimmed Lichen (Various Species)

The term "rimmed lichen" refers to several different species of lichen, often within the Aspicilia genus. The name arises from the rim-like structure sometimes found surrounding the apothecia (fruiting bodies) of certain lichens.

Considerations for Pets

  • Wirework cloches, sometimes "copper rimmed," are used to protect plants from animals like deer, rabbits, squirrels, birds, slugs, and snails.

Scientific Classification and Nomenclature

  • Kingdom: Fungi
  • Family: Hymeneliaceae (for some Aspicilia species) or Lecanoraceae (for Rhizoplaca) or Megasporaceae (for some calcareous rimmed lichen)
  • Genus: Several genera are mentioned in association with "rimmed lichen", including:
    • Aspicilia
    • Rhizoplaca
  • Some species mentioned include:
    • Aspicilia reptans (Rimmed Lichen)
      • Synonyms: Lecanora reptans, Lecanora ryrkaipiae
    • Aspicilia annulata (Rimmed Lichen)
    • Aspicilia calcarea (Calcareous Rimmed Lichen)
    • Aspicilia cinerea (Cinder Lichen)
    • Caloplaca cerina (Gray-rimmed firedot lichen)

Distribution and Habitat

  • Rimmed lichens can be found in various locations, including Ireland, France, California (Sagehen Creek Basin), and the valley of the Dry Frio River.
  • Some, like Aspicilia calcarea, are specifically found on limestone rock.

Morphological Characteristics

  • Lichens are a symbiotic combination of a fungus and algae (green or blue-green).
  • Crustose lichens, in particular, may have a rim surrounding their cup-shaped apothecia.

Quirky Facts

  • Some lichens, like Pannaria conoplea (Mealy-rimmed shingle lichen), have a jelly-like thallus (body) when wet that shrinks and becomes wrinkled when dry.
  • The genus Rhizoplaca are commonly called rimmed navel lichens.

Interactions with Other Organisms

  • Wirework cloches are used to protect plants from animals, including deer, rabbits, squirrels, and birds, suggesting these animals may interact with plants and lichens in gardens.
