Source-reviewed species profile
Chaga Inonotus obliquus
Black, charcoal-like sterile growth on the trunk rather than a typical cap-forming fruit body. This profile covers broad field features, season and habitat for learning.
Where can I find chaga?
Mainly on living birch in boreal woodland.
In Mycoverse you can select Chaga and compare candidate search areas using a species-specific assessment of rainfall, estimated soil moisture, temperature, forest type, tree signals, canopy cover, terrain and season. Where source coverage is available, the assessment also uses historical species observations. Historical observations are historical data, not recent finds.
Images, text and app suggestions cannot confirm a species or food safety.
