Lichens are symbiotic organisms made up by the association of microscopic green algae or cyanobacteria and filamentous fungi. There is evidence that lichens might involve a controlled form of parasitism of the algal cells.

Lichens live on various surfaces: soil, trees, rocks, and walls. They are often the first to settle in places lacking soil, constituting the sole vegetation in some extreme environments such as found at high mountain elevations and at high latitudes.

Lichens are fungi that live in a symbiotic association with an autotrophic green alga or cyanobacterium (the "photobiont") or — in some cases — both.
The fungal partner (the "mycobiont") in most lichens (98% of them) is an ascomycete.

Nostoc punctiforme is a cyano-bacterium that enters into symbiotic associations with fungi and lichens; these relationships are relevant to carbon cycling and sequestration in tundra.

In England before the Industrial Revolution trees are often covered with light colored lichens. As a result light moths were favored because they were hard to see on the bark of trees whereas the dark moths were easy to see; birds ate the dark moths.

Over the next 100 years, trees with dark trunks became dominant because lichens have difficulty growing in polluted environments. With a substantial increase in dark trees in urban areas, the dark form of the moth increased in abundance.
