Mushrooms with a blue cut

Features of mushroom picking

Poisoning with poisonous mushrooms can lead not only to an upset digestive system, but also to severe intoxication of the body with poisons, leading not only to health problems, but even to death. Therefore, to go to the forest for mushrooms should be armed with a sufficient supply of knowledge about the characteristics of the edible mushrooms found in this area, their appearance, places of growth and harvesting seasons.

Noticing that the mushroom turns blue on the cut, and having certain knowledge, it is easy to determine its nutritional value and effect on the body.

Nature awarded many organisms with similar features, so the best way to avoid the sad consequences is to study the differences of each species and observe the basic rules of collection:

  • it is better for a beginner to go to the forest for mushrooms accompanied by more experienced comrades;
  • collection points are chosen away from highways, industrial enterprises and environmentally polluted places, because all mushrooms are able to accumulate toxins from the environment (only in different quantities);
  • they collect only young intact specimens, avoiding old and overripe ones that have low taste indices;
  • if there is the slightest doubt about the suitability of the fungus for consumption, it is left in place so as not to spoil the entire harvest and not endanger its health.

Types of mushrooms

When examining a mushroom, one draws attention to its size and shape, the color of the fruiting body, the structure of the cap and legs, the aroma, the color of the plates and pulp at the break. One of the features of these organisms is the ability of the pulp to change color when damaged, which occurs due to the oxidation of certain substances in air (more precisely, with the participation of atmospheric oxygen).

If the mushroom turns blue on the cut, it is carefully inspected to determine the type. This ability is both edible and poisonous.

The opinion that blueing is a sign of the presence of toxins in the fetal body is erroneous.

Edible varieties

Of the edible popular species, boletus, oak trees, Polish mushrooms, and a mushroom listed in the Red Book with the strange name "bruise" - bluish gyroporas, have the ability to turn blue on a cut. Their main characteristics are as follows:

  1. Boletus: are considered valuable and tasty products, have many varieties. One of them is red or red-headed. The leg of the mushroom turns blue on the cut, and after a while it turns black. Outwardly, it is noticeable and bright. The cap of an adult fetus is pillow-shaped, reaches 30 cm in diameter. It has a red-brick color, the surface of the fetus is smooth and velvety in dry weather. Its leg is thick and massive, has a scaly surface. It grows in deciduous forests, at the base of aspen trunks.
  2. Speckled Dubovik: Belovet family. The hat is large, cushion-shaped, uneven gray-yellow color. Leg at base thick, with mesh surface. When damaged, the flesh with a yellowish quickly becomes blue-green, and then blackens. It occurs mainly under oaks and lindens.
  3. Polish white mushroom: a valuable and rare representative. It has a convex hat up to 12 cm in diameter, which becomes almost flat in adulthood. Color - from light brown to brown. The leg is straight, slightly thickened at the base. The pulp is dense, with a yellow tint. If damaged, the fungus first turns blue on the cut, then becomes brown, has a pleasant mushroom smell.
  4. Bruise: a vivid representative of the pig family. It has a wide and almost flat hat from 5 to 15 cm in size, from white-yellow to brownish-gray. Its surface in an adult specimen is slightly cracked. The leg is low, up to 10 cm, cylindrical in shape. When broken, the flesh changes color from white to bright blue.

Irina Selyutina (Biologist):

Blue gyroorus is rarely found in Europe and North America. In the post-Soviet space, it can be found in the European part of the former USSR, in the Caucasus and the Far East. Due to its limited distribution throughout Russia, the bruise mushroom is known only to a small number of lovers of “silent hunting”. However, it can be an excellent basis for preparing a wide variety of mushroom dishes. When dried, the aroma of gyroporus is enhanced several times (water leaves, only the dry pulp components remain) and the mushroom can be used as a seasoning after grinding into a powdery mass using a coffee grinder or a manual mill for spices.

These edible mushrooms, like a number of others, are mycorrhiza forming with different species of woody plants, giving each other the possibility of full existence, because mushrooms supply water and mineral substances from the soil, and plants "give" part of the polysaccharides synthesized during photosynthesis.

Poisonous representatives

Satanic mushroom turns blue when damaged

There are poisonous mushrooms that tend to turn blue when damaged. Their brightest representative is the satanic mushroom. It is found infrequently, but has a bright appearance. His hat reaches 30 cm in diameter, has a convex-prostrate shape and a velvety surface. Its color is white-gray, sometimes it has a yellowish tint. The leg is tall and massive, barrel-shaped. The mushroom immediately turns blue on the cut, then the flesh acquires a pinkish tint.

Another mushroom from the genus Oily - yellowish-brown moss, it belongs to the conditionally edible species. It will not cause severe poisoning, but if improperly processed, it can provoke problems with the gastrointestinal tract. The fruit body is small, the cap is convex in shape at the edges. The yellowish-brown surface of the cap with small scales is slippery and sticky. The leg is smooth, from 3 to 10 cm in height. If you press on the spongy layer under the hat, it acquires a blue tint.

The most dangerous and poisonous - pale toadstool, fly agaric, false foam, bile fungus and others. They should beware and know the features of their description. Such a mushroom never turns blue on a cut.


Mushrooms are a healthy and nutritious natural product. They contain a large number of vitamins, minerals and essential amino acids. Being a low-calorie product, mushrooms are used in diet and vegetarian nutrition. And the high protein content has made them popular in special sports diets. In addition, the beneficial substances and compounds contained in mushrooms are successfully used in folk and traditional medicine.

Fruit bodies that change the color of the pulp to blue are not always unsuitable and dangerous to eat.


Gathering mushrooms in the forest, it is necessary to carefully and carefully examine each cut specimen before sending it to the basket. A change in color with damage to the fruiting body is not an indispensable sign of its danger. Only knowledge of all the characteristics in the complex will allow you to navigate and make the right choice.
