Description
Cyrtidula is a group of lichens that typically grow on tree bark. They form small, dark spots or lines on the surface. These lichens are known for their unique spore-producing structures, which are flask-shaped and partially embedded in the lichen body. Cyrtidula species are often used by researchers to study air pollution levels in different environments.
