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.
