Identification in 5 steps

Agaricus mushrooms are gilled mushrooms with a white to brownish, dry cap, a ring on the stem and gills that are pink when young and chocolate brown later. The white species, such as the field mushroom, are popular edible mushrooms. Because they can be mistaken for deadly poisonous destroying angels and the poisonous yellow-stainer, safe identification is essential.

FamilyAgaricaceae
  1. Cap. The cap skin is white, yellowish or brown, smooth, fibrous or scaly, but always dry and never slimy. The cap margin is not grooved. In some species the cap skin turns yellow under pressure.
  2. Underside. The gills are free from the stem and mostly crowded. When young they are pale grey to pink; as the spores ripen they turn chocolate brown to purplish black. They are never white.
  3. Stem, ring and volva. The stem is central, separates easily from the cap and bears a ring or at least veil remnants. It can be bulbous at the base, but has no volva.
  4. Smell and taste. Some species smell of aniseed, almonds or phenol. A smell of phenol or ink points to poisonous species.
  5. Flesh and colour change. The flesh can stay white or turn yellow or red when damaged.

Lookalikes

Group profile: the genus includes popular edible mushrooms, but also poisonous species. White Agaricus mushrooms are easily mistaken for the deadly poisonous white destroying angels. Remember: Agaricus mushrooms never have white gills and no volva at the stem base.

In the kitchen

Fried, steamed or in sauces. Use only young, firm mushrooms with pale pink to brown gills, and cut every mushroom open lengthways before cooking. Cook for at least 15 minutes.

No reliable information on drying. Risk of confusion with deadly poisonous white destroying angels. Species that turn yellow in particular accumulate heavy metals in high amounts. Mushrooms that smell of phenol or turn chrome yellow at the stem base are poisonous.

Frequently asked questions

Are white Agaricus mushrooms from the woods or meadows edible?

Many species of the genus are edible, others are poisonous. White Agaricus mushrooms may only be eaten if they are identified with certainty and cooked thoroughly.

How do you recognise an Agaricus?

By the free gills that are pink when young and chocolate brown later, the ring on the stem and the lack of a volva at the stem base.

How do you recognise the poisonous yellow-stainer?

It smells of carbolic acid, that is, of phenol, and the flesh in the stem base is bright chrome yellow.

What can white Agaricus mushrooms be mistaken for?

For the deadly poisonous white destroying angels, which always have white gills and a volva at the stem base, and for the poisonous yellow-stainer.
