Fungal toxins

In deserts a wide variety of poisonous mushroom species can exist, such as the Fly Agaric Mushroom (Amanita muscaria). Most likely, the poisons contained within this fungus are there to act as a deterrent against grazers, particularly useful in deserts where resources are limited. Other examples of toxin producing fungi are species of Aspergillus, which have the potential to produce the highly carcinogenic aflatoxins.
