Chaga mushroom, popular in our country, or birch mushroom, is a sterile, that is, sterile, form of the species Tinder mowed, or Inonotus obliquus, and belongs to the department of Basidiomycetes.

Description and characteristic

Most often, chaga is found on a birch. Thanks to how the mushroom looks and where it is located, Chaga received the household name "black birch mushroom." However, this type of fungus can also affect other deciduous trees, including alder, mountain ash, beech, elm and maple.

According to the description of the fungus, the formation of chaga occurs as a result of damage to the wood by the parasitic fungus Inonotus obliquus, the spores of which can germinate when exposed to damaged areas of the tree bark. As a result of fungal lesions, irregularly shaped growths are formed, the diameter of which can reach 0.45 m with an average thickness of 12-14 cm.

The surface of the formed growths is characterized by black staining and the presence of characteristic numerous crackings. The interior is dark brown with a smooth transition to a reddish-brown color. White veins penetrate the entire thickness of the growth.

The fungus grows for several years, and the result of its vital activity is the death of the host plant. In this case, the fungus’s own fruit body is formed on the opposite side of the trunk. The size and shape of the formed growths mostly depend on the type of damage to the tree before infection with a fungus fungus.

Chaga birch grows quite intensively. Mushroom picking should be best in winter. It is not recommended to collect mushrooms from felled or dry wood. In the process of collecting birch chaga should be chopped with an ax at the stem of the tree.

When processing the fungus, the first thing to do is to clean the loose, light-colored, unsuitable part. It is also necessary to remove residual wood and plant debris. Chaga prepared in this way needs to be divided into several parts and dried, observing the temperature regime at the level of 50-60 ° C. The standard shelf life of dried mushrooms does not exceed a couple of years.

Chaga is widely used in modern herbal medicine. It is important to remember that the fungus growing at the base of the tree has practically no healing and medicinal power, so the collection should be carried out from the highest plants. A properly dried product should have no more than 10-12% moisture and about 20% of extractive elements.
