Description of the hat
Suillus rubinus is a small mushroom, with a cap diameter of 4-8 cm. Young specimens have a hemispherical or rounded cap, but with age it opens, turning into a flat, pillow-like one. At the same time, the sharp wavy edges of the cap are turned inside out and bent up. The skin covering the top of the cap is dry, looks like suede to the touch, cannot be removed with a knife.

The lower part of the cap (hymenophore) is a tubular structure with large pores, painted in a deep red-pink color. When pressed, the color of the tubes does not change. Reproduction of a ruby oiler is carried out by means of microscopic rounded or wide-elliptical ocher-colored spores, which are formed in a brownish spore powder.
Leg description
The ruby oiler has a strong, low leg, shaped like a mace or a cylinder, tapering towards the base. Its diameter usually does not exceed 3 cm, the average height is 3-6 cm. Specimens with a curved stem are often found. The surface is smooth, in rare cases pubescent, painted in a thin, barely perceptible reticular pattern of carmine-pink color, the bottom is ocher-yellow. With a longitudinal section of the mushroom, you can see that the flesh of the leg has an uneven color. At the base, it is deep yellow, the rest is pinkish.
Ruby oiler is rarely found on the territory of Russia, it is considered a new species, its area of growth is still subject to study and monitoring. Despite the lack of data, the ruby oiler is listed in the Red Book of the Russian Federation.

- vitamin B2 (riboflavin);
- vitamin B6;
- carbohydrates;
- lecithin;
- amino acids;
- fatty acid;
- essential oils.
100 g of the product contains only 19.2 kcal, the use of oil helps to eliminate uric acid from the body and reduce cholesterol levels. However, biologists strongly recommend refraining from collecting these mushrooms, since the species is on the verge of extinction.
Where and how does the ruby oil can grow
Rubinoboletus is widespread in some European countries, it is extremely rare on the territory of the Russian Federation, mainly in the Far East and Transcaucasia. The only confirmed place of growth of this fungus in Russia is a forest belt in the vicinity of the village. Oatmeal in the Amur region.
The mushroom prefers oak or mixed forest with a predominance of birch, beech, linden, chestnut, hawthorn, holly. In rare cases, it grows in a pine forest with a small admixture of deciduous species. This type of oil can be found in the undergrowth with a dense herb cover, where a large number of grasses are present. The soil loves fertile, it is most often found on silty loams, on floodplains and in places where livestock regularly graze.
Ruby boletus - mushrooms growing singly or 2-3 pcs. Cases of the development of mycelium Suillus rubinus on well-decomposed oak wood have been recorded. Rubinoboletus does not bear fruit every year, the best conditions for active growth are warm and rainy summers and early autumn.
Inexperienced mushroom pickers can confuse ruby oil can only with a gall mushroom. The species are similar in structure of the fruiting body, but the twin does not have the characteristic pinkish coloration of the stem, and the tubular layer becomes reddish-brown when pressed.
