Stubble Rosegills (Volvopluteus gloiocephalus) are a common sight on ovals and lawns. Their shiny, silvery caps make them easy to spot. Luckily, too, they are one of the mushrooms that cane found at almost any time of day. They have a characteristic, sack like structure at the base of their stem. This is called a ‘volva’ amd is the remnant of the veil that once covered the gills when the mushroom was immature.

Their moist, white flesh has a pleasant, but not strong taste (some sources suggest ‘radish-like’) and is best added to soups. The mushrooms do not preserve well for long periods and are not good for drying.

You’ll also see Stubble Rosegills listed in books under the names Volvariella gloiocephala or Volvaria speciosa var. gloiocephala or even Volvariella speciosa var. gloiocephala depending on who wrote them , where and when.

Warning

The only other mushrooms occurring in this area that have a volva at the base are species of Amanita, the ingestion of which can be fatal. The young Stubble Rosegills have white gills, as do the Amanitas but those of the Rosegills turn pink as the mushroom matures, Those on an Amanita stay white. Please be very cautious.
