Are there any mushrooms commonly found in backyards that are toxic to squirrels?

Squirrels are cute and friendly creatures that can often be found scampering around backyards, parks, and forests. They have a diverse diet that includes nuts, seeds, fruits, and even fungi. In fact, squirrels are known to eat a variety of mushrooms, but are there any mushrooms commonly found in backyards that are toxic to squirrels? Let's explore this question in more detail.

To begin with, it's important to note that squirrels possess a remarkable ability to distinguish between safe and toxic mushrooms. They have a built-in instinct that helps them avoid consuming mushrooms that could be harmful to their health. However, this does not mean that all mushrooms commonly found in backyards are safe for squirrels to eat.

One commonly found mushroom in backyards is the Amanita muscaria, also known as the fly agaric. This mushroom is easily recognizable by its bright red cap with white spots. Amanita muscaria contains toxins that can be harmful to humans and various other animals, including squirrels. If a squirrel were to consume this mushroom, it could potentially experience symptoms such as vomiting, diarrhea, and even neurological effects.

Another toxic mushroom that can be found in backyards is the Amanita phalloides, also known as the death cap mushroom. This mushroom is extremely poisonous and is responsible for the majority of mushroom-related fatalities worldwide. It contains a potent toxin called amatoxin, which can cause severe liver damage and even death in both humans and animals.

While these toxic mushrooms can be found in backyards, it's important to note that squirrels have a natural aversion to them. Their instinctual knowledge of what mushrooms to avoid keeps them safe from ingesting these harmful fungi. Squirrels are likely to steer clear of any mushrooms that have a strong odor, unusual colors, or are slimy in texture.

It's also worth mentioning that the presence of toxic mushrooms in a backyard is relatively rare. In most cases, mushrooms that grow in lawns or gardens are harmless species that serve as decomposers of organic matter. These mushrooms may not be appetizing to squirrels, but they generally pose no threat to their health.

In conclusion, while there are toxic mushrooms that can be commonly found in backyards, squirrels are generally cautious when it comes to consuming fungi. Their natural instinct helps them avoid mushrooms that could be harmful to their health. However, it's important for homeowners to be aware of any toxic mushrooms in their yard and take appropriate measures to remove them if necessary. By doing so, they can create a safe environment for both squirrels and other wildlife that may frequent their backyard.


How can you identify toxic mushrooms that could be harmful to squirrels?

Squirrels are known to be curious creatures, and they often explore their surroundings in search of food. While they primarily feed on nuts, seeds, fruits, and vegetables, they may also come across mushrooms during their foraging adventures. It is essential to be able to identify toxic mushrooms that could be harmful to squirrels to ensure their safety. Here are a few steps to help you in identifying potentially toxic mushrooms:

  • Educate yourself: Before attempting to identify mushrooms, it is crucial to educate yourself about the various types of toxic mushrooms in your area. Familiarize yourself with the common varieties and their unique characteristics. Online resources, field guides, or joining a local mycology club can provide valuable information and support.
  • Examine the cap: The first step in identifying mushrooms is to examine the cap. Toxic mushrooms often have distinct characteristics. Look for any bright colors, unusual textures, or structures such as scales or warts. Take note of the cap's shape and whether it is convex, flat, or bell-shaped.
  • Observe the gills: Gills underneath the cap are another important characteristic to consider. Some toxic mushrooms have gills that may be a different color than the cap or have an attached or free attachment to the stem. Note the color, shape, and arrangement of the gills to further aid in identification.
  • Check the stem: The stem of a mushroom can provide valuable clues about its toxicity. Some toxic mushrooms have a distinctive bulbous base or a ring around the stem. Others may have a hollow or solid stem. Note any unique features of the stem, such as color, texture, or any other noticeable abnormalities.
  • Look for a veil or cortina: A veil or cortina refers to a thin membrane that covers the gills of some mushrooms when they are young. This structure can help differentiate between different species. Some toxic mushrooms may have remnants of the veil or cortina present, while others may not.
  • Evaluate the spore print: Obtaining a spore print can provide additional information when identifying mushrooms. A spore print is a representation of the mushroom's spores, which can vary in color. To obtain a spore print, simply take a mature mushroom and place the cap on a piece of paper or glass overnight. The spores will drop, leaving a print that can help identify the mushroom.
  • Seek expert guidance: If you are unsure about the identification of a mushroom, it is always best to consult with an experienced mycologist or mushroom expert. They can provide accurate identification and help determine whether a mushroom is toxic or safe for squirrels.

Remember, it is crucial to prioritize the safety of squirrels and any other wildlife when dealing with mushrooms. Even if a mushroom is identified as non-toxic, it is best to observe and ensure that the squirrels do not exhibit any signs of illness after consuming it. If you suspect that a squirrel has ingested a toxic mushroom, contact a wildlife expert or veterinarian immediately for assistance.

Examples of toxic mushrooms that could be harmful to squirrels include the Amanita species, such as the Death Cap (Amanita phalloides) and the Destroying Angel (Amanita bisporigera). These mushrooms contain potent toxins that can be lethal if ingested. Other toxic mushrooms include the False Morel (Gyromitra esculenta), which contains a chemical that can cause severe gastrointestinal distress and liver damage.

In conclusion, identifying toxic mushrooms that could be harmful to squirrels requires knowledge, observation, and caution. By following these steps and seeking expert guidance when needed, you can ensure the safety and well-being of the squirrels in your area.


What are the potential dangers of squirrels consuming poisonous mushrooms found in the backyard?

Squirrels are known for their agility, curiosity, and ability to adapt to various environments.
