Fragile amanita  (Amanita friabilis)

Endemic to Europe, this fungus is widespread but extremely rare throughout its range (4).

Fragile amanita has a mycorrhizal relationship with alder and is therefore always found in association with this tree. It has been found with Alnus glutinosa, A. incana and A. crispa in alder swamps and with A. viridis in sub-alpine habitat (3).
