Chamaeota is a genus in the Pluteaceae family of small to medium sized mushrooms. They have a central stem, free gills, smooth pink spores, and a partial veil that usually forms an annulus (ring) on the stalk. Chamaeota can be distinguished from Volvariella by its lack of a volva and from Entolomataceae by its free gills and smooth spores.

Members of Chamaeota are extremely rare. Most species are tropical but at least two species exist in the United States.

The type species is Chamaeota xanthogramma (Ces.) Earle [as 'xanthogrammus'] (1909).
