Possible lookalikes Could be confused with any of the poisonous Agaricus - such as the Yellow Stainer (Agaricus xanthodermis)or the Inky Mushroom (Agaricus moelleri), but these smell unpleasant of phenol or bottled ink and/or stain strongly yellow, particularly in the base of the stem, when bruised or cut

Always stay safe when foraging. You need to be 100% sure of your identification, 100% sure that your foraged item is edible, and 100% sure that you are not allergic to it (it is good practice to always try a small amount of any new food you are consuming). If in doubt, leave it out!
