Short description: Swellings of fungus cultivated by fungus-growing ants
French depiction of gongylidia and staphylae in different sizes.

Gongylidia (singular gongylidium) are hyphal swellings of fungus cultivated by higher-attine genera of fungus-growing ants. This fungus no longer exists naturally outside the ant colonies.

Developing larvae feed on the gongylidia and distributed throughout the colony to feed workers, soldiers, and the queen.[1] They are ellipsoid, about 30-50 micrometres in diameter,[2] rich in lipids and carbohydrates derived from the leaves,[3] and are produced in clusters (called staphylae).[4]
