 Kuehneromyces mutabilis is found in Australia, Asia (in the Caucuses, Siberia, and Japan), North America, and Europe.In Europe, it can be found from Southern Europe to Iceland and Scandinavia.Though edible, "K. mutabilis" cannot be recommended as it could be confused with the deadly poisonous "Galerina autumnalis" or "Galerina marginata", even by people who are quite knowledgeable.
