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.
The caps of this mushroom can be fried or used for flavouring in sauces and soups (the stems being considered too tough to eat).

Although a typical K. mutabilis is easily distinguished from a typical G. marginata by the "booted" stipe which is shaggy below the ring (see photos), this character is not reliable and G. marginata can also have scales. The main differences are:
