Guide to Poisonous Mushrooms

Taylor Lockwood's new dvd entitled, "The Good, the Bad, and the Deadly" is available at: www.kingdomoffungi.com Amanita bisporigera or "The Death Angel"
Mostly east coast fruitings but widespread and prolific. Has been mistaken for many other mushrooms though it is easily identified--if you know what to look for.
It's also known as "The Destroying Angel."
marmorata
Amanita marmorata is known from Hawaiian Casuarina forests and responsible for pet deaths. Suspected and analyzed as toxic to humans though no statistics for this--yet.
ocreata
Amanita ocreata a.k.a. The Western Death Angel. This one is mostly white with some light shading on the cap, it is responsible for one death in Santa Barbara this year. The problem with the western Amanitas is that they are big and sumptuous looking to the inexperienced mushroom hunter.
Amanita phalloides or "The Death Cap" is responsible for 80-90% of mushroom caused deaths worldwide.
Death Caps look beautiful and have been mistaken for various edible mushrooms from Agaricus species (field mushrooms, etc.) to edible Lepiotas.
They are widespread but more common on the west coast.
Phalloides are most prevalent from mid-autumn until late winter.
Amanita virosa (Known as The Death Angel, as well) These are known from Europe and Japan although the names are often applied to North American mushrooms.
Galerina autumnalis The Deadly Galerinas--Should be hard to mistake for edible mushrooms. There are easy and definitive ways to tell them apart with deadly consequences if you can't.
Galerina marginata contains the same deadly poisonous toxins as Amanita phalloides. It appears on conifer stumps and occasionally on the stumps of broadleaf trees.
Gyromitra esculenta and Gyromitra infula (false morels) are mildly toxic on the west coast, more toxic on the east coast and deadly in parts of Europe. They are most likely mistaken by people who are looking for morels. They are also eaten in the northwest and other parts of the world but the toxins are cumulitive.
Gyromitra infula
