Chamaeota
Encyclopedia
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).
Pluteaceae
The Pluteaceae are a family of small to medium-sized mushrooms which have free gill attachment and pink spores. Members of Pluteaceae can be mistaken for members of Entolomatacae but can be distinguished by their angled spores and attached gills...

Annulus (mycology)
An annulus is the ring like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remaining part of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. An annulus may be thick and membranous, or it may be cobweb-like...

Volvariella
Volvariella is a genus of mushrooms with deep salmon pink gills and spore prints. They lack a ring, and have an Amanita-like volva at the stem base. Some species of Amanita look similar, but Amanita has white spores and often have a ring. Since the gills of young Volvariella are white at first,...

Volva (mycology)
The volva is a mycological term to describe a cup-like structure at the base of a mushroom that is a remnant of the universal veil. This macrofeature is important in wild mushroom identification due to it being an easily observed, taxonomically significant feature which frequently signifies a...

Entolomataceae
The Entolomataceae, also known as Rhodophyllaceae are a large family of pink spored terrestrial gilled mushrooms which includes the genera Entoloma, Rhodocybe, and Clitopilus. The family collectively contains over 1500 species, the large majority of which are in Entoloma...
