Placidium

Placidium is a genus of crustose to squamulose to almost foliose lichens. The genus is in the Verrucariaceae family. Most members grow on soil (are terricolous), but some grow on rock (saxicolous). The fruiting bodies are perithecia, flask-like structures immersed in the lichen body (thallus) with only the top opening visible, dotting the thallus.
