Rimmed Lichen Overview

This page provides information about various lichens referred to as "rimmed lichens," including details about their classification, distribution, and characteristics.

Considerations for Pets

  • Mentions of cloches (specifically "Copper rimmed cloche - lichen green") suggest that some rimmed lichens or plants associated with the name are found in gardens, potentially accessible to pets.
  • Wirework cloches might pose a hazard if ingested or if a pet becomes entangled.

    • Rhizoplaca: Rimmed Navel Lichens (genus)
    • Lecanactis salicina: Old Wood Rimmed Lichen
    • Aspicilia annulata: Rimmed Lichen
    • Lecanora albopruinosa: Rimmed Lichen
    • Lecanora californica: California Rim Lichen
    • Pertusaria velata: Rimmed Wart Lichen
