Field mushroom  (Agaricus campestris)

This widespread species is a close relative of the species of mushroom that is typically sold in shops (Agaricus bisporus) (3). The field mushroom has a creamy-white cap and stem, and bright pink or chocolate-brown coloured gills (2). The cap takes on a brownish tinge as it ages, and becomes more flattened in shape (3). Although edible, this species is easily confused with the deadly poisonous fungus the destroying angel (Amanita verna) when in the 'button' stage (3).

WARNING: Many species of fungus are poisonous or contain chemicals that can cause sickness. Never pick and eat any species of fungus that you cannot positively recognise or are unsure about. Some species are deadly poisonous and can cause death within a few hours if swallowed.
