Scientific Name: Buellia dialyta
Family: Physciaceae
Category: Lichen
Growth: Lichenous
Duration:
Other Names:
Disc Lichen (Buellia spp.)
Disc lichens, also known as button lichens, belong to the genus Buellia. This genus is part of the family Physciaceae. The name \"disc lichen\" refers to their distinctive disc-shaped fruiting bodies (apothecia).
Quirky Facts
- The term \"disc lichen\" references the circular, disc-shaped apothecia responsible for sexual reproduction and spore dispersal in these organisms.
- Lichens, although plant-like in appearance, are a symbiotic relationship between fungi and algae or cyanobacteria.
Considerations for Pets and Children
- Lichens can grow on various surfaces, including rocks, trees, and soil, potentially making them accessible to pets and children in outdoor environments.
- Some lichens produce secondary metabolites, and although this text highlights antimicrobial properties, it\'s essential to note that any lichen extract should be handled with care.
Taxonomy and Nomenclature
- Scientific Name: Buellia De Not.
- Common Names: Disc lichen, Button lichen, Black Disc Lichen, Stilling\'s Disc Lichen, Common Button Lichen.
- Family: Physciaceae
- Kingdom: Fungi (Lichens are a symbiotic partnership, but the fungal partner determines classification)
- Synonyms/Alternative Names:
- 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.
- Grows on various substrates, including rocks, trees (e.g., poplar), and soil.
Morphological Characteristics and Growth Habits
- Lichens are lichenous.
- Apothecia are typically disc- or cup-shaped, used in lichen identification.
- Apothecia color varies, including black and yellow. Some may be pruinose (covered in a frosty powder).
- Thallus can be necrotic and thin, potentially having a thalline veil.
- Some species exhibit a crustose growth form, growing closely attached to the substrate.
Interactions with Other Organisms
- The text mentions the re-establishment rate of reindeer lichen species after soil preparation in Pinus-lichen clear-cut areas, indicating a relationship with pine trees (Pinus).
- Antimicrobial activity against certain organisms has been observed.
