Description
Placopyrenium is a group of lichens that form crusts on rocks and soil. They are often found in alpine and arctic environments. Some species have a unique ability to grow on metal-rich substrates, including old mining sites. Their thallus (body) can be dark-colored, sometimes with a bluish or greenish tinge. Placopyrenium plays a role in early stages of soil formation in harsh environments.
