Rimmed Lichen (Various Species)

The term "rimmed lichen" encompasses several species of lichens, not a single specific plant. This makes a precise definition challenging. However, the information below provides a general overview based on the provided text.

Considerations for Pets and Children

Wirework cloches, sometimes described as "copper rimmed" or "lichen green," are mentioned as being used to protect plants from deer, rabbits, squirrels, and birds. These cloches may pose a physical hazard if mishandled or played with. Exercise caution when using them in areas accessible to pets and children.

Nomenclature and Taxonomy

  • Common Name: Rimmed Lichen (applies to several species)
  • Scientific Names: The text references several species, including:
    • Aspicilia annulata
    • Aspicilia calcarea (Calcareous Rimmed Lichen)
    • Aspicilia reptans
  • Family: Hymeneliaceae (for Aspicilia species), Lecanoraceae (for Rhizoplaca) and Megasporaceae (for some Calcareous Rimmed Lichens)
  • Synonyms/Alternative Names:
    • Lecanora reptans and Lecanora ryrkaipiae are mentioned as other names for Aspicilia reptans.

Distribution and Habitat

  • The provided text mentions observations of calcareous rimmed lichen (Aspicilia calcarea) and other rimmed lichens in various locations including:
    • Sagehen Creek Basin, California
    • The valley of the Dry Frio River
    • Olonne-sur-Mer, Vendee, Pays de la Loire, France
    • Idaho (specifically noting the absence of Aspicilia reptans)
    • Pyrenees, France
    • Lookout Mountain, Ochoco National Forest
  • Specific habitats mentioned include limestone rock.

Morphological Characteristics

  • The text mentions that apothecia (fruiting bodies) of some lichens have a distinctive rim.
  • Some rimmed lichens are crustose (forming a crust-like layer on the substrate).
  • Pannaria conoplea is described as having a jelly-like thallus when wet, that shrinks and become strongly wrinkled.

Interactions with Other Organisms

  • The text mentions wirework cloches used to protect plants from being eaten by deer, rabbits, squirrels, and birds. This suggests that some plants, and indirectly the lichens growing on them, can be food sources for these animals.
  • Lichens are a combination of a fungus and a green algae or a blue-green algae or a combination of all.

  • The text references several resources for further information, including:
    • MO (likely Missouri Botanical Garden)
    • ToL (Tree of Life Web Project)
    • BHL (Biodiversity Heritage Library)
