Distribution and Habitat
- The genus is found in various regions, including Great Britain, Ireland, North America, South Korea, Brazil, Guatemala, Venezuela, China (Yunnan), and the Aegean.
- Fuscidea cyathoides is often found on bare rock surfaces, including mountain tops and rocky seashores.
Morphological Characteristics
- Fuscidea cyathoides has a pale grey thallus, often with brown tinges.
- Fuscidea lightfootii has a bright green to brownish crustose thallus.
- Fuscidea kochiana has thallus almost white to pale grey, often tinged brown, cracked areolate.
- Fuscidea lygaea has a thin, usually cracked, pale- to dark-grey thallus.
Ecological Role
- Some Fuscidea species are part of specific ecological communities, such as the Rhizocarpon geographicum-Fuscidea lygaea community.
Interactions with Other Organisms
- Fuscidea lichens are saxicolous, meaning they grow on rocks, and can be associated with bryophyte assemblages.
