Extract from Wikipedia article: Inonotus obliquus, commonly known as chaga (a Latinisation of the Russian word чага), is a fungus in the family Hymenochaetaceae. It is parasitic on birch and other trees. The sterile conk is irregularly formed and has the appearance of burnt charcoal. It is not the fruiting body of the fungus, but a sclerotium or mass of mycelium, mostly black because of the presence of massive amounts of melanin. Some people consider chaga to be medicinal, though this is subject to debate as it has not been tested in human clinical trials and there are potential hazards from its consumption.
Inonotus obliquus, also known as chaga mushroom, is a parasitic fungus that grows on birch trees. In St. Petersburg, Leningrad Oblast, and north-western Russia, it is commonly found on Betula pendula and Betula pubescens. The fungus forms a sterile conk that can grow up to 40 cm in diameter, with a rough, black exterior and a soft, orange interior. It is widely distributed in the region, particularly in areas with abundant birch forests, such as the Karelian Isthmus and the Valdai Hills. The fungus is typically found on mature trees, often at the base of the trunk or on branches, and can cause significant damage to its host tree over time.
