Strigula Lichen

Strigula is a genus of lichens, representing a symbiotic association between algae and fungi.

Considerations for Pets

  • Strigula lichens can grow on leaves, potentially including magnolia leaves, in areas where pets might have access.

Considerations for Children

  • Strigula lichens can grow on leaves, potentially including magnolia leaves, in areas where children might have access.

Taxonomy and Nomenclature

  • Scientific Name: Strigula Fries
  • Common Name: Strigula Lichen
  • Family: Strigulaceae
  • Kingdom: Plants (Plantae) – note this may be a general listing based on association with plants, further information needed to clarify.
  • Division: Ascomycota
  • Synonyms/Alternative Names:
    • Arthopyrenia affinis auct. N. Amer. (for Strigula jamesii)
  • Taxonomic Rank: Variety (e.g., Strigula stigmatella var. stigmatella)

Distribution and Habitat

  • Strigula species are found in various locations, including:
    • New Zealand
    • Dorset (UK)
    • Mississippi (USA)
    • Madeira and Gomera
    • Taiwan
    • Southeastern Australia
    • Europe and Macaronesia
    • USA and Canada
    • Greece
    • Indian Subcontinent
    • South Korea
  • They can be foliicolous (growing on leaves), endolithic (growing inside rocks), or found on other surfaces like magnolia leaves.
  • Some species are calcicolous, meaning they prefer growing on limestone or other calcium-rich substrates.

Morphological Characteristics

  • Some species, like Strigula macaronesica, have an almost linear thallus growing along leaf margins.
  • Strigula macaronesica also has unusually small obclavate asci.
  • Strigula elegans can be found foliicolous on Magnolia grandiflora.
  • The lichen can appear as grayish-white and darker "crusts" on leaf surfaces.

Interactions with Other Organisms

  • Strigula represents an association between algae and fungi. The alga uses photosynthesis to produce food, while the fungus provides structure and support.
  • Strigula species can be found growing on green algae.
