Wisconsin's rare lichens

There are 48 lichens on Wisconsin's Natural Heritage Working List, including four that are tracked by the Natural Heritage Inventory. Lichens are a symbiotic combination of two or occasionally three organisms: a fungus and a photosynthetic algae and/or cyanobacteria. As such, they don't fit into the traditional definition of a plant.
