Picking your own mushrooms can be an enjoyable way of obtaining these nutritious fungi. However, it’s important to be on the alert for poisonous mushrooms. Some poisonous varieties look very similar to their edible relations. The purpose of this article is to provide information about poisonous mushrooms and how you can identify them.
Death Cap
Only a few bites of a Death Cap mushroom are enough to kill someone. The symptoms will not occur until one or two days after eating and death will follow in up to one week. Death Caps have a round silver cap on top and a white stem. They grow close to the ground under shrubs and bushes.
What makes them more hazardous is that they grow well in towns and cities. Unlike most poisonous plants and mushrooms, these mushrooms don’t have a bitter taste. Once the symptoms have started to appear, the damage is already underway.
Destroying Angel
Like Death Caps to which they are related, Destroying Angel mushrooms are very poisonous. With a white, bulbous cap and a thick stem, Destroying Angels have a resemblance to white button mushrooms and meadow mushrooms. Young Destroying Angels can be mistaken for Puffballs. The distinguishing features of Destroying Angels are a white stem and gills, where the gills are not attached to the stem. They also have a broken membrane at the base of the stem.
Most deaths caused by mushrooms are due to Destroying Angels since their poison is difficult to treat. By the time symptoms occur, around five hours after ingestion, the damage to the liver and kidneys is irreversible.
Jack O’Lantern
Jack O’Lantern mushrooms are orange in color. They grow in clusters and have gills. This helps to differentiate them from Chanterelles, which are similar in appearance and edible, but which do not have proper gills.
Dying after eating a Jack O’Lantern is very unusual, but it’s still worth avoiding these poisonous mushrooms.
Other differences between a Jack O’Lantern or Chanterelle are that the gills of the Jack O’Lantern are said to glow in the dark; Chanterelles not only don’t glow in the dark, they also don’t have actual gills – they have structures which resemble gills.
False Morels
Morels are tender and full of flavor – they can be found near dead trees in colder climates in the spring. However, false morels (scientific name Gyromitra esculenta) grow in similar environments; this is a category that encompasses several species of poisonous morel-like mushrooms.
Eating a false morel doesn’t always result in death. Some people deliberately cook these mushrooms just like a traditional morel. However, the combination of a mushroom with a relatively high level of poison and a person with a high level of sensitivity to that poison can result in symptoms such as diarrhea, vomiting, and, finally, death.
Fly Agaric
The Fly Agaric mushroom (scientific name Amanita muscaria) is very distinctive because of its red-colored cap with white spots. It is often dried and eaten for its hallucinogenic effects.
This mushroom is poisonous, although fatalities rarely occur since only eating large amounts of the raw mushroom will result in death.
Conclusion
Being able to identify poisonous mushrooms from non-poisonous varieties is a key skill. A good guide is always useful. Be alert when collecting mushrooms – if you’re not sure about a mushroom, then don’t pick it.
