Learning in the Leaves Iden/fica/on-‐ Agaricus bisporus Imbach -‐ Cul/vated (Bu=on) Mushroom
Dis$nguishing Features • Ini$ally hemispherical, becoming convex and eventually fla:ening. At maturity,
the cap diameter is usually between 5 and 10cm. • The crowded gills are narrow and free; ini$ally pink they turn reddish and then
chocolate brown as the fruitbody matures. • The stem is 3 to 6cm tall and 1.5 to 2cm wide. Below the insubstan$al
membranous double ring, the surface of the stem is flaky.
Interes$ng Facts • It surely goes without saying that this is a good edible mushroom and one of the $ny minority of edible fungi that
are considered safe to eat raw. The very pale-‐capped mushrooms sold in most supermarkets are a derived form of Agaricus bisporus, which in the wild has a brown cap as shown in the main picture, above. When fully expanded, the caps are some$mes referred to as Portobello Mushrooms (some$mes spelt Portobella).
