Meadow Mushroom

Agaricus campestris

Edible

Also called field mushroom, pink bottom.

The meadow mushroom is the wild relative of the supermarket button mushroom: a white cap with pink gills that age to chocolate brown, on a short stem with a thin ring. It grows in lawns and pastures, and its deadliest lookalikes are the white amanitas.

Field marks

What to look at

Cap, underside and stem show in a photo. The spore print does not, and it is often the deciding check.

Cap
Rounded, then convex to flat, white to grayish white, smooth to silky or with fine fibers or small scales. Dry, not sticky.
Underside
Gills free from the stem, crowded, bright pink when young, turning chocolate brown and then blackish brown. Very young buttons are covered by a thin white veil.
Stem
Short, white, smooth, tapering slightly toward the base, with a thin, fragile ring that often disappears. No bulb and no cup.
Flesh
Firm and white, sometimes turning slightly pinkish when cut. It does not turn bright yellow. Smell pleasant.
Spore print
Chocolate brown.
Size
Cap 1 to 4 inches wide (2.5 to 10 cm); stem 1 to 2.5 inches tall (2.5 to 6 cm).

Edibility

What the field guides say

Edible

Field guides list the meadow mushroom as edible. The same guides record its dangerous lookalikes: white Amanita species such as the destroying angel, which contain amatoxins and have white gills and a cup at the base, and the yellow stainer, which causes gastrointestinal upset. Pink to brown gills and a chocolate brown spore print separate the meadow mushroom from the amanitas.

This page states what field guides record. It is not advice to eat, taste or handle anything, and a photo cannot settle edibility. If someone has eaten a wild mushroom that may be toxic, call poison control (1-800-222-1222 in the US) right away, before symptoms start: the deadliest species act hours later.
