The semi-white mushroom or, as it is also called, the yellow boletus (Boletus impolitus) belongs to the Boletaceae family. In some areas of our homeland it is called lemongrass (lemon). Genus: boletus. We have known about this mushroom since childhood, since there are a lot of references to boletus mushrooms in Russian literature. However, this mushroom has a more common name in science and is called semi-white.
There are many boletus species, but it is the semi-white species that deserves special consideration. It has nutritional qualities and properties that no other mushroom in the family can boast of. Let's find out what exactly we are talking about.
Description and photo of the Half-white mushroom
How do you understand that you have found a boletus in the forest? What characteristic differences will set it apart from other mushrooms?
Experienced mushroom pickers will probably tell you that you need to pay attention to the appearance of the boletus mushroom. This is true. And according to some characteristics, you can actually understand that this is exactly the representative of the family.
Hemileccinum impolitum - from Latin.
hat
Let's start the description with the cap. It has an impressive diameter of up to 20 cm. Average individuals have a diameter of about 15 cm. The diameter of the cap is approximately 5 cm, in thickness, but at a more mature age it grows to 20 centimeters.
The hat is very fleshy, yet elastic. However, with age it becomes more pliable.
Over time, the boletus becomes completely flat as it matures.
If you run your hand over the cap, you will realize that it is somewhat wrinkled and smooth. At the same time, the color of the cap itself has a yellow-brown tint.
As soon as dry weather sets in and the cap dries out, cracks will form on it. However, during wet weather the cap becomes covered with mucus again.
The cap gives off a pleasant aroma, which is very similar to the smell of champignons.
Leg
As for the stem, it is mostly solid, tuberous and at the same time thick. Its height also varies. At an early age, the boletus stalk is about 4 or 5 cm in height. With age, the mushroom rises to a height of up to 12 cm. It is clearly visible among grass and plants.
As for the girth of the leg, it can reach from 2 to 6 cm in diameter, that is, it is very stable. The leg has a yellowish color, but becomes browner with age. On the very surface of the leg there are peculiar nets, which imply small brown scales.
Pulp
As for the flesh of the militant, it is very dense, without a characteristic smell. At the same time, the color of the flesh is bright yellow, and the older the mushroom, the more its color stands out. However, if you cut into a mushroom and leave its softness to interact with oxygen, it will very soon take on a bluish tint.
As for the spores, they are stored in special tubes, the length of which is about 2 cm. These tubes are very smooth and have a slightly bluish tint.
The spores themselves are also smooth and fusiform. The spore powder itself does not have an olive color, however, it acquires it with age.
Distinctive features
The tubular mushroom has many distinctive features:
- strong, fleshy structure of the fruit stem and cap element, their structure suggests large sizes;
- attractive to parasites and pests;
- the spongy surface of the spore-bearing part can change color with age or when pressed;
- ability to accumulate large amounts of water;
- strong mushroom aroma and bright taste of the pulp;
- the number of edible species predominates.
Lamellar mushrooms differ from tubular mushrooms in their hymenophore, which is presented in the form of separate radial plates. The difference between them is also evident in the description of the pulp: spongy ones are denser, while plastic ones are susceptible to crumbling. Differences are also observed in the shape of the cap, where a convex hemisphere is more common for tubular ones, and a horizontal, flat upper part for lamellar ones. Similarities are observed in the color scheme of the edible fruiting bodies.
Irina Selyutina (Biologist):
The tubular-type hymenophore is characteristic of boletes and tinder fungi. It is represented by a mass of tubes opening downward, etc. sending ripened fungal spores into life. Almost always the tubes grow together, resulting in the formation of a solid mass, but in the liverwort the tubes are easy to separate from each other; they are free, because do not fuse with the side walls. Important systematic features are the size and shape of the pores. They can be regular, round or angular in shape. The color of the pores may differ from the color of the layer of tubules, which will be especially noticeable in the section of the hymenophore.
A less popular group of marsupials that grow above and below ground. The spores ripen inside the mushroom body, which looks like a ball or oval. Therefore, tubular saprotrophs, as well as lamellar saprotrophs, belonging to the same basidial group, are strikingly different from marsupials.
Edibility of the semi-white mushroom
Yellow boletus belongs to the category of edible mushrooms. It is used in the preparation of various dishes, and it is absolutely safe for people.

Yes, and this mushroom is very high in calories, if you consume it especially in the afternoon, you will gain extra pounds, especially if you abuse it.
