The map lichen is a crust lichen, the thallus lies close to the ground or grows through it. The species is bright yellow to olive green. It can cover large areas on stones. The lichen is divided into small angular fields, which are separated by a black border and pull through the lichen body. At the edge of the fields black edged fruiting bodies are sunk. The appearance of this structure is reminiscent of geographically separated areas on a map. Like many lichens, it has extremely slow growth. It grows depending on the location per year only 0.25-0.6 mm radially outward. It can reach an age of over 1,000 years and can be used to date the decline of glaciers. If the growth rate at a location is known, the last ice cover can be calculated from the largest specimens.
