The kingdom fungi has very few organisms in the marine environment. Most fungi are land based. These include mold and yeast.

Fungi lacks the photosynthetic pigments. Many fungi can be decomposers. They take dead organic material and break it down

When fungi lives in a symbiotic mutalism with cyanobacteria lichens are formed. Symbiotic mutalism means when two organisms can live together through symbiosis. Each organism gives the other something it needs to live. These lichens are unicellular organisms and now have chlorophytes because of the blue-green algae. Algae or bacteria provide rich molecules from photosynthesis.

The fungi can dissolve surfaces. When it is provided with nutrients and structure it can produce filaments to attach to rocks. These lichens can dissolve the surface of the rocks they attached to. Lichens are usually seen on rocks and trees.

They are environmental indicators. When you don't see them on rocks and plants it is because of pollutants in the air. As early as the mid 1800's, scientists became aware that lichens were uncommon in areas within and surrounding large towns and cities. They began to recognize that air pollution emitted from these urban areas was affecting the colonization and growth of these organisms. The lichen does not do well in big cities like Los Angeles because of the air pollution.
