Disc Lichen (Genus Buellia)

Lichens within the genus Buellia are commonly referred to as disc lichens or button lichens. The information below provides an overview of what is known about these fascinating organisms.

Considerations for Pets

  • Some species feature disc-shaped structures (apothecia).

Considerations for Children

  • Some species feature disc-shaped structures (apothecia).

Taxonomy and Nomenclature

  • Scientific Name: Buellia De Not.
  • Common Names: Disc lichen, Button lichen
  • Family: Physciaceae (for at least one species, Buellia nigra)
  • Synonyms: Buelliopsis (e.g., Buelliopsis papillata for Buellia papillata)

Distribution and Habitat

  • The genus Buellia has a widespread distribution.
  • Observed on the Diamond Coast, South Africa.
  • Found in Chiricahua National Monument.
  • Observed growing on a live poplar tree in South Glenmore Park.

Morphological Characteristics

  • Characterized by necrotic thalline material (thalline veil).
  • Discs (apothecia) are typically black and epruinose (lacking a powdery surface coating).
  • Apothecia can be disc- or cup-shaped fruiting bodies, involved in sexual reproduction.
  • Some species have yellow, disc-shaped apothecia.
  • Growth forms are generally shaped like a disc, usually with a rim around the edge.
  • Crustose growth habit: growing so closely attached to the substrate that it is impossible to separate without damage.

Interactions with Other Organisms

  • Reindeer lichen species are found in Pinus-lichen clear-cut areas.
  • Can have a potential antifungal effect.

  • Buellia papillata
  • Buellia stillingiana (Stilling's Disc Lichen, also known as Common Button Lichen)
