The Death Cap is
responsible for the most mushroom poisonings
in the world. It looks a lot like other mushrooms which
people eat (compare it to the Honey Mushroom on this site).
It has a cap
up to six inches wide, and a stalk
up to five inches tall. The cap can be yellowish, brownish,
whitish, or greenish in color. It is often sticky to the
touch. Underneath the cap, this mushroom has white
gills
(feathery things). At the base of the stalk is a white
cup. Death Caps are seen from
September to November underneath pines, oaks, dogwoods, and
other trees. Copyright, Fred

Stevens Like all mushrooms, Death
Caps are only part of the fungus. Most of the fungus is in
the soil or wrapped around tree roots. These tiny
thread-like parts, called mycelia,
are there all year. The mushroom that you see is like the
flower on a plant. It "blooms" at certain times of the
year. The mushrooms contain
spores,
which are like seeds on a plant. The spores spread and grow
new fungi. Death Caps have a foul smell which attracts flies
and other insects. When the insects touch the gills, spores
stick to them. Then, when the insects fly away, the spores
go with them. Each spore may get a chance to grow into a new
fungus.



Death Caps are a type of fungus which has a mycorrhizal relationship with trees. This special relationship means that the fungus wraps its mycelia around tree roots. The fungus then gives the tree special nutrients from the soil that it couldn't get by itself. This helps the tree stay healthy and strong. In return, the fungus can pull different nutrients from the tree roots that it would not get on its own. Therefore, the fungus and tree help each other. This is why you almost always see Death Caps underneath trees. You may see just a few, or there may be hundreds of mushrooms under the same tree.
Some scientists believe the Death Cap was introduced from Europe, others believe it is a native species.

Relationship to Humans:
Death Caps are extremely poisonous and will likely kill you if you eat one! REMEMBER, NEVER EAT A MUSHROOM FROM THE WILD, even if you think you know what it is. People who die from Death Caps or other poisonous mushrooms almost always ate it because they thought it was something else.
Someone who eats a Death Cap will not feel any symptoms for 10 to 14 hours. Then the person will experience vomitting, diarrhea, and cramps. After awhile, these symptoms will go away and the person will feel fine. They are not fine. Three or four days after eating the mushroom, the person will have kidney or liver failure. He/she will die five to ten days after eating the Death Cap.
Death Caps help us indirectly, by helping trees grow. These trees provide fresh oxygen, and food for animals.
