List of deadly fungus species

Although many people have a fear of mushroom poisoning by "toadstools", only a small number of the many macroscopic fruiting bodies commonly known as mushrooms and toadstools have proven fatal to humans.

This list is not exhaustive and does not contain many fungi that, although not deadly, are still harmful. For a less-detailed list of fungi that include non-deadly poisonous species, see List of poisonous fungi.
