Rimmed Lichen

This page provides information about various lichens referred to as "rimmed lichens," focusing on their classification and related data.

Scientific Name and Common Names

  • Scientific Name: Several species are mentioned, including Aspicilia reptans, Aspicilia calcarea, Aspicilia annulata, and Aspicilia quartzitica.
  • Common Name: Rimmed Lichen (used generically for several species). Other common names mentioned include Calcareous Rimmed Lichen, Contorted Rimmed Lichen, Rimmed Navel Lichens, Old Wood Rimmed Lichen, White Rimmed Lichen, Gray-Rimmed Firedot Lichen, Rimmed Shingle Lichen, and Multicolored Rim-Lichen.

Taxonomy and Nomenclature

  • Kingdom: Fungi (Lichens are a symbiotic association between a fungus and algae).
  • Family: Hymeneliaceae (for some Aspicilia species), Lecanoraceae (for Rhizoplaca), and Megasporaceae (for one entry regarding CALCAREOUS RIMMED LICHEN).
  • Synonyms/Alternative Names: Lecanora reptans and Lecanora ryrkaipiae are listed as other names, likely synonyms, for Aspicilia reptans.

Distribution and Habitat

  • The text mentions locations such as Ireland, Sagehen Creek Basin (California, USA), the valley of the Dry Frio River, France, Olonne-sur-Mer (Vendee, Pays de la Loire, France), Lookout Mountain (Ochoco National Forest), and Wisconsin. This suggests a widespread distribution for various rimmed lichen species.
  • Specific habitats mentioned include limestone rock and rocks atop Lookout Mountain.

Morphological Characteristics

  • The term "rimmed" refers to the rim surrounding the cup-shaped apothecia (fruiting bodies) in some crustose lichens.
  • Rhizoplaca species are called rimmed navel lichens.
  • Some lichens have a jelly-like thallus (body) when wet, which shrinks and becomes wrinkled when dry.

Interactions with Other Organisms

  • Lichens are a symbiotic combination of a fungus and algae (either green algae or blue-green algae, or a combination of both).

Further Information

  • The text references several resources for further information: MO (likely Missouri Botanical Garden), ToL (Tree of Life Web Project), BHL (Biodiversity Heritage Library), WikiSpecies, the Lichen Flora of the Greater Sonoran Desert Region, and Wisconsin's Natural Heritage Working List.
