In mycology, referring to an organism that grows in on on the ground: Some fungi are geogenous because they grow in the earth, and are therefore distinct from those that thrive on living forms of life not in the soil.

Outdated, the science of the formation of the Earth: Geogeny especially refers to the earlier developmental phases of the Earth and its role in the solar system.

In mycology (branch of botany that studies fungi and fungus-caused diseases), a family of fungi belonging to the order Helotiales (famous blue-green cup fungi that makes its home on oaks): The Geoglossaceae consist of the species commonly known as the "earth tongue" which are found on soil, on rotting wood, and on plant leaves.

Any ground-constructed example of rock art by using rocks, stones, earth, etc.: Examples of ,geoglyphs can be intaglios or rock alignments, straight lines, geometric shapes, and other representative designs found on the desert plain.

Geoglyphs can be formed by piling up materials on the ground surface or by removing surface materials and most suggest a largely ceremonial function.
