Poisonous Mushrooms to Avoid
When foraging for edible mushrooms in Iowa, it is important to be able to identify the poisonous ones to avoid. Eating poisonous mushrooms can lead to serious illness or even death. Here are some of the poisonous mushrooms that are commonly found in Iowa:
False Morel
The False Morel (Gyromitra esculenta) can be mistaken for the true morel, but it is actually highly toxic. It contains a toxin called gyromitrin, which can cause symptoms such as nausea, vomiting, diarrhea, headache, dizziness, and even coma or death. The False Morel can be identified by its brain-like cap and wrinkled, convoluted surface.
Destroying Angel
The Destroying Angel (Amanita bisporigera) is one of the deadliest mushrooms in Iowa. It contains a toxin called amatoxin, which can cause liver and kidney failure. Symptoms may not appear until several hours after ingestion, and by then it may be too late to seek medical attention. The Destroying Angel can be identified by its white cap and stem, and its ring around the stem.
Green Russula
The Green Russula (Russula aeruginea) is a highly toxic mushroom that can cause severe gastrointestinal symptoms such as nausea, vomiting, and diarrhea. It can also cause neurological symptoms such as tremors, convulsions, and coma. The Green Russula can be identified by its greenish cap and stem, and its brittle, easily broken flesh.
Galerina Marginata
The Galerina Marginata (Galerina autumnalis) is a small, brown mushroom that contains a toxin called amatoxin, which can cause liver and kidney failure. It can be mistaken for a harmless mushroom, but it is actually highly toxic. Symptoms may not appear until several hours after ingestion, and by then it may be too late to seek medical attention. The Galerina Marginata can be identified by its brown cap and stem, and its ring around the stem.
Earthballs
Earthballs (Scleroderma spp.) are not deadly, but they are toxic and can cause gastrointestinal symptoms such as nausea, vomiting, and diarrhea. They can be mistaken for truffles, which are edible, but they are actually toxic. Earthballs can be identified by their round, hard, brownish-black fruiting bodies.
It is important to be able to identify these and other poisonous mushrooms in Iowa to avoid them when foraging. When in doubt, it is best to err on the side of caution and not eat any mushroom that you are not absolutely certain is safe to eat.
Foraging Guidelines
Foraging for mushrooms in Iowa can be a fun and rewarding experience, but it is important to follow some guidelines to ensure that it is done safely and sustainably. The Iowa State University Extension and Outreach has published the “Safe Mushroom Foraging” guide, which provides guidance on identifying and understanding the characteristics of Iowa’s mushrooms, as well as best practices for searching for them in the wild. Here are some key guidelines to keep in mind:
- Always obtain permission from the landowner before foraging on private property.
- Only pick mushrooms that you can positively identify as safe to eat. If you are unsure about the identity of a mushroom, do not eat it.
- Avoid picking mushrooms in areas that may be contaminated with pollutants or toxins, such as near roadsides or industrial sites.
- Use a basket or mesh bag to carry your mushrooms, rather than a plastic bag, which can cause them to sweat and spoil.
- Cut mushrooms at the base of the stem, rather than pulling them out of the ground, which can damage the mycelium and prevent future growth.
- Leave some mushrooms behind, especially those that are small or immature, to allow them to mature and spread spores for future growth.
- Clean your mushrooms thoroughly before cooking them, removing any dirt or debris with a soft brush or cloth. Do not wash them, as they can absorb water and become soggy.
By following these guidelines, you can enjoy the bounty of Iowa’s mushrooms while also protecting the environment and ensuring your safety. Always remember to exercise caution and use common sense when foraging, and consult the “Safe Mushroom Foraging” guide for more detailed information.
Seasonal Availability of Mushrooms
Mushrooms are available throughout the year in Iowa, but their availability varies according to the season. Spring and fall are the best seasons for mushroom hunting in Iowa. During the spring season, morels are the most commonly found edible mushrooms in Iowa. They are usually found in woodland areas and near dead or dying trees. Morels have a unique flavor and are highly valued by mushroom hunters.
In addition to morels, gray and shaggy mane mushrooms are also commonly found in the spring season. Gray mushrooms have a smooth cap and a stem that is attached to the cap’s center. Shaggy mane mushrooms have a bell-shaped cap and a stem that is attached to the cap’s bottom. Both of these mushrooms are edible and have a mild flavor.
During the fall season, black-staining polypore mushrooms are commonly found in Iowa. These mushrooms have a dark brown cap and a white stem. They are usually found in woodland areas and near dead or dying trees. Black-staining polypore mushrooms have a slightly bitter taste but are still considered edible.
It is important to note that not all mushrooms found in Iowa are safe to eat. Some mushrooms can be poisonous and can cause serious health problems. It is important to properly identify mushrooms before consuming them. Mushroom hunters should also be aware of the regulations regarding mushroom hunting in Iowa and obtain the necessary permits before hunting.
Mushroom Habitats in Iowa
Iowa is home to a variety of mushroom habitats, including deciduous forests, parks, and areas with ash trees. These habitats provide the necessary conditions for mushroom growth, such as moisture, shade, and organic matter.
Deciduous forests are a common habitat for mushrooms in Iowa. These forests are composed of trees that lose their leaves each year, such as oak, hickory, and maple. The fallen leaves and other organic matter provide a rich source of nutrients for mushrooms to grow. Some of the mushrooms that can be found in deciduous forests in Iowa include morels, chanterelles, and oyster mushrooms.
Parks are another habitat for mushrooms in Iowa. These areas often have a mix of trees and open spaces, which can create a diverse range of mushroom species. Parks with water features, such as ponds or streams, can also provide a moist environment for mushrooms to thrive. Some of the mushrooms that can be found in parks in Iowa include shaggy manes, chicken of the woods, and lion’s mane mushrooms.
Ash trees are a specific habitat for certain types of mushrooms in Iowa. Ash trees are susceptible to a disease called emerald ash borer, which can kill the tree and create a dead and decaying environment for mushrooms to grow. Some of the mushrooms that can be found growing on dead ash trees in Iowa include oyster mushrooms, turkey tail mushrooms, and artist’s conk.
Overall, Iowa has a diverse range of mushroom habitats, each with its own unique species of mushrooms. It is important to remember that not all mushrooms in these habitats are safe to eat, and proper identification is necessary before consuming any wild mushrooms.
