The spore powder is deep pink, soon giving a pink tint to the initially pale gills.
The gills are free from the stipe.
There is no volva or ring (exception: the rare recently reclassified North American species P. mammillatus, previously Chamaeota sphaerospora).[4]
Microscopically, they often have abundant, distinctive cystidia. The spores are smooth and roughly egg-shaped.
Pluteus is separated from Volvariella due to the lack of a volva, and from Entoloma by growing on wood and by microscopic features (Entolomas have angular spores).
Naming
The name Pluteus was established in 1837 by the founding mycologist Elias Magnus Fries at a time when agaric mushrooms were first being assigned to different genera.
[5]
The Latin word "pluteus" has various meanings related to military protective structures and its signification here may be that of a shield (the shape of the cap).

Remarks on particular species
Some of these mushrooms are edible including P. petasatus and P. cervinus, though most people rate their taste and consistency as average at best.
Pluteus cervinus is the best known species in Europe and North America.
