Volvopluteus gloiocephalus, commonly known as the big sheath mushroom, rose-gilled grisette, or stubble rosegill, is a species of mushroom in the family Pluteaceae. For most of the 20th century it has been known under the names Volvariella gloiocephala or Volvariella speciosa, but recent molecular studies have placed it as the type species of the genus Volvopluteus, newly created in 2011. The cap of this mushroom is about 5–15 cm (2–6 in) in diameter, varies from white to grey or grey-brown, and is markedly sticky when fresh. The gills start out as white but they soon turn pink. The stipe is white and has a sack-like volva at the base. Microscopical features and DNA sequence data are of great importance for separating V. gloiocephalus from related species. V. gloiocephalus is a saprotrophic fungus that grows on grassy fields and accumulations of organic matter like compost or woodchips piles. It has been reported from all continents except Antarctica.
