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 $ny minority of edible fungi that are considered safe to eat raw. The very palecapped mushrooms sold in most supermarkets are a derived form of Agaricus bisporus, which in the wild has a brown cap as shown in the main picture, above. When fully expanded, the caps are some$mes referred to as Portobello Mushrooms (some$mes spelt Portobella). [informa$on collated from the First Nature Website: www.firstnature.com ]

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).
