Gilled mushrooms
Field mushroom
Agaricus campestris · also known as: Meadow mushroom
EdibleApproved for sale
A good edible mushroom. Pick only fruit bodies whose gills are already pink or brown – young, closed specimens with white gills can be confused with deadly poisonous white amanitas. Do not pick next to busy roads (pollution). The name “pieczarka łąkowa” is recommended in newer mycological literature (Wojewoda 1987); in legislation and everyday speech – “pieczarka polna”.

Look-alikes: what it can be mistaken for
Destroying angel Deadly poisonous high risk of confusion
A deadly poisonous white amanita. It has gills that are always white, a white spore print and a volva at the bulbous stem base. The risk concerns mainly closed, young fruit bodies.
Step-by-step comparison: Field mushroom or destroying angel →Death cap Deadly poisonous high risk of confusion
Young and white (var. alba) death caps have white gills, a hanging ring and a sac-like volva. Never pick “field mushrooms” with white gills.
Step-by-step comparison: Field mushroom or death cap →Yellow stainer Poisonous medium risk
The yellow stainer, when rubbed (especially at the stem base), immediately turns chrome-yellow and smells of carbolic/ink, more strongly when cooked.
Step-by-step comparison: Field mushroom or yellow stainer →Deadly fibrecap Deadly poisonous low risk
White young fruit bodies growing along roads and in parks may resemble young field mushrooms; the field mushroom has pink, then chocolate-brown gills, a ring, and does not turn red along its fibres.
