Disc Lichen (Various Species)
The term "disc lichen" or "button lichen" refers to various species within several genera of lichens, characterized by their disc-shaped fruiting bodies.
Considerations for Pets
- Lichens in general have been known to be extracted in acetone, methanol, and ethanol.
Nomenclature and Taxonomy
- Common Names: Disc lichen, Button lichen, Black Disc Lichen, Common Button Lichen, Rock Disk Lichen, New Mexican disc lichen
- Genus: Buellia
- Family: Physciaceae (for Buellia nigra)
- Synonyms: Buelliopsis papillata (for Buellia papillata)
Distribution and Habitat
Disc lichens exhibit a widespread distribution, occurring in diverse environments. Specific examples include:
- Howard County (referencing Buellia stillingiana)
- Diamond Coast (referencing Black-disc lichen)
- Chiricahua National Monument (referencing New Mexican disc lichen)
- South Glenmore Park (lichen growing on a live poplar tree)
Morphological Characteristics
- Characterized by disc-shaped fruiting bodies (apothecia). The apothecia are often described as disc- or cup-shaped.
- Some species have yellow, disc-shaped apothecia.
- Some have a thalline veil (necrotic thalline material).
- Discs can be black and epruinose (without a powdery surface).
- Some species form twisted rows of separate discs.
Quirky Facts
- The Downs lichen trail was funded by the British Lichen Society, the Bristol Naturalists' Society and included "another disc on the smaller branches."
- One source humorously notes an image that resembles a dragonfly wing pattern, but is used to showcase the "Captive Lichen Disc rotating!"
Interactions with Other Organisms
- One study investigates the re-establishment rate of reindeer lichen species following soil preparation in Pinus-lichen clear-cut areas, indicating an association with pine trees.
- Lichens can grow on trees, as evidenced by a lichen found on a live poplar tree.
- Some studies explore the antifungal activity of lichen extracts, indicating potential interactions with fungal species.
- Lichens are known to host fungal spores within their fruiting bodies.
