Disc Lichens (Genus Buellia)

Lichens in the genus Buellia are commonly known as disc lichens or button lichens.

Considerations for Pets

  • The text mentions "necrotic thalline material," which could indicate the presence of decaying organic matter within the lichen structure. This might attract pets, though the implications of ingestion are not specified.

Taxonomy and Nomenclature

  • Scientific Name: Buellia De Not.
  • Common Names: Disc Lichen, Button Lichen
  • Family: Physciaceae (mentioned in relation to Buellia nigra)
  • Group: Lichen
  • Symbol: BUELL
  • Synonyms:
    • Buelliopsis papillata (for Buellia papillata)

Distribution and Habitat

  • The genus Buellia has a widespread distribution.
  • Observed on the Diamond Coast (in reference to "Black-disc lichen, Diamond Coast - 2012")
  • Found in Chiricahua National Monument ("Lichens of Chiricahua NM. Guide to Lichens of Chiricahua National Monument")
  • Observed growing on a live poplar tree in South Glenmore Park.
  • Found in England ("Gray-green disc lichen ... British Lichen Society - BLS Lichen Database: England")

Morphological Characteristics

  • Disc lichens are characterized by disc-shaped apothecia (fruiting bodies) that are often black and epruinose (lacking a powdery surface coating).
  • Apothecia are used in the identification of lichens as part of sexual reproduction.
  • The thallus (main body) can be strongly split, forming twisted rows of separate discs.
  • Some disc lichens have yellow, disc-shaped apothecia.

Ecological Role

  • Mentioned in the context of reindeer lichen re-establishment after disc trenching and soil preparation in clear-cut areas.

Interactions with Other Organisms

  • Grows on poplar trees alongside other lichen species (Lecanora sp.).
  • The text mentions a study on the "re-establishment rate of reindeer lichen species following conventional disc trenching and HuMinMix soil preparation in Pinus-lichen clear-cut."

Quirky Facts

  • The text references "Captive Lichen Disc rotating!" as a pattern from a dragonfly wing, highlighting an interesting visual similarity.
  • The Downs lichen trail was funded by the British. Lichen Society, the Bristol Naturalists&#39 Society.
