Taxonomy and Nomenclature

  • Scientific Name: Rimularia Nyl.
  • Family: Rimulariaceae, Agyriaceae (in some classifications)
  • Kingdom: Fungi
  • Synonyms:
    • For Rimularia insularis: Lecidea insularis Nyl., Lecidea intumescens (Flotow) Nyl.

Common Names

  • Rimularia Lichen

Distribution and Habitat

  • Found in various locations, including:
    • North and West regions
    • Montane rocks, especially schist
    • Northwestern Europe
    • Southern subpolar region
    • Western Canada
    • Taiwan
    • New South Wales, Australia (eucalypt forest for Rimularia exigua)
    • Aegean (e.g., Thasos for Rimularia furvella)
    • Central Siberian Biosphere Reserve
    • Tasmania (endemic species)
    • Saskatchewan

Morphological Characteristics

  • Thallus: Can be grey-brown, grey to dark brown, or black. Often cracked-areolate.
  • Prothallus: Black prothallus often visible between the areoles.
  • Apothecia: Minute, black, set in the thallus surface. Sometimes somewhat... (text incomplete).
  • Asci: Cylindrical-clavate, Rimularia-type, 8-spored.
  • Ascospores: Ellipsoid to broadly ellipsoid.

Interactions with Other Organisms

  • Rimularia insularis forms a photosynthetic thallus on lichens of the Lecanora rupicola group. It is considered a parasite of numerous crustose lichen species.
  • Rimularia asteriphila grows on bark (corticolous).
  • Rimularia furvella grew on other lichens.
