There are many different types of mycotoxins. Of 14 distinctive types of mushroom poisoning found worldwide, so far about 10 distinctive patterns of reactions to mycotoxins have been observed in North America. However, since most mushroom species are rarely eaten, many toxins are poorly documented and syndromes not yet observed in North America may turn up as more and more people experiment with eating wild mushrooms. NAMA maintains a case registry where you may report instances of mushroom poisoning.
