  • Champignons. Champignons, such as wood or field mushrooms, are edible mushrooms that look almost exactly like white death caps.
  • Paddy Straw. Paddy straw mushrooms are basically identical to death caps. Spore print: Paddy straws have pink spore prints, while death caps have white spore prints.
  • Green Russalas. Some people mistake death caps for russalas, but the two types of mushroom are fairly easy to tell apart if you know what you’re doing.
  • Caesar’s Mushroom. Caesar’s mushrooms are generally bright yellow or orange and easy to distinguish from mature death caps; but both mushrooms look nearly identical when in the egg stage.
  • Albino Blushers. This type of mushroom is closely related to the death cap, but it doesn’t contain the same harmful toxins so it is edible.
  • Puffballs. Puffball mushrooms are white and can sometimes be confused with young death caps still in the egg stage.
  • False Death Cap. False death caps look almost exactly like true death caps, and both should be avoided as they are both toxic.
  • Destroying Angel. The destroying angel is right up there with the death cap as being one of the most poisonous mushrooms in the world.

To identify death cap mushrooms, you need to take into account 5 identifying characteristics: White gills that don't turn brown, cup-like volva at the base, greenish yellow cap, large skirt, and a white spore print.
