Chaga mushroom, or scientifically referred to as Inonotus obliquus, is a fungus in the Hymenochaetaceae family. Chaga mushroom is known to grow primarily on birch trees in cold climates. Chaga mushroom grows wild in Russia, Siberia, Northern Canada, Northern Europe, Korea, and Alaska. The Chaga mushroom produces a dark woody growth known as a conk. The Chaga mushroom conk has been used in several medical practices and has several purported Chaga health benefits. Chaga is also known by names like Inonotus obliquus, clinker polypore, and sterile conk. The Chaga mushroom has an irregular shape and the outer appearance of burnt charcoal. The burnt charcoal appearance is due to high amounts of melanin. Interestingly, the inside of the Chaga mushroom is typically a bright orange color.
