Description
Birchbark dot lichen is a genus of lichens that primarily grow on tree bark. These lichens form thin, dark crusts that can be difficult to spot without close inspection. They have a unique reproductive structure called perithecia, which are small, flask-shaped containers that house spores. Birchbark dot lichen species are often found in temperate regions and play a role in monitoring air quality due to their sensitivity to pollution.
