Considerations for Children

  • This lichen grows on rocks, concrete and trees.

Distribution and Habitat

  • Xanthoria parietina has a wide distribution and is found in many locations.
  • It is commonly observed on rocks, concrete, and trees.
  • Often found near cattle farms due to its preference for ammonia.
  • Can be especially prolific, forming noticeable orange lichen belts.
  • Also found on coastal rocks in New Zealand.

Morphological Characteristics

  • Foliose (leafy) lichen forming large, rounded patches up to 10 cm across.
  • Features wide, round-lipped marginal lobes.
  • The thallus (body) ranges from yellowish-green to golden-yellow or orange, sometimes appearing grey in shade.
  • Lacks isidia or soredia.
  • Apothecia (fruiting bodies) are usually present, featuring a dark orange disc surrounded by a lighter edge.

Ecological Role

  • Grows in profusion in seabird colonies because they identify hunting perches of birds.

Quirky Facts

  • The orange color of Xanthoria parietina is due to the production of the pigment parietin.
  • Lichens have been described as "dual organisms" due to their symbiotic relationship between a fungus and an alga.

Interactions with Other Organisms

  • Grows in a symbiotic relationship with algae, where the alga is contained within the hyphae of the fungus.

Traditional and Potential Uses

  • Pigments from colorful lichens, including orange ones like Xanthoria parietina, can be extracted by boiling and used to dye wool and other fibers.
  • Parietin, the orange pigment found in this lichen, may have potential as an anti-cancer drug because it interferes with certain cancer-related processes.
