Ringless honey mushrooms, also known as Armillaria tabescens, are generally considered non-toxic to dogs, but ingestion can cause mild gastrointestinal symptoms like vomiting, diarrhoea, and lethargy. However, it is important to note that there are look-alike mushrooms that may not be safe for consumption, and proper identification is crucial. Honey mushrooms obtained from the roots of dead trees are safe for human and animal consumption, but those found on fruit tree roots contain cyanide and should be avoided. Dogs have reportedly died after consuming raw honey fungus, so it is essential to seek veterinary care if your dog exhibits any signs of distress or mushroom poisoning, which can be life-threatening.

Ringless honey mushrooms are generally considered non-toxic to dogs
Honey mushrooms can be found in the wild, growing on the roots of dead or alive trees. They are widely spread across the United States and Canada's cooler regions, particularly in Oregon, where they are known to grow abundantly for a short period of about one to two weeks. They are also found in New Jersey and Texas, typically in mid-September and late October, respectively.
Ringless honey mushrooms, also known as Armillaria tabescens or Desarmillaria caespitosa, belong to the Physalacriaceae family. They are known for their bioluminescent, glowing figs, and yellow caps. While they are generally edible, cooking may be required to make them safe for consumption, as they are known to cause mild gastrointestinal symptoms such as vomiting or diarrhea in dogs.
If your dog is suspected of ingesting ringless honey mushrooms, monitor them closely for any signs of distress, such as lethargy, excessive drooling, or abdominal pain. If symptoms worsen or persist beyond 24 hours, seek veterinary care immediately. It's important to prevent dogs from accessing wild mushrooms and to educate yourself on toxic plant identification to reduce the risk of accidental poisoning.

Ingestion can cause mild gastrointestinal symptoms like vomiting or diarrhoea
Ringless honey mushrooms are generally considered non-toxic to dogs, but ingestion can cause mild gastrointestinal symptoms like vomiting and diarrhoea. It is important to monitor your dog closely for any signs of distress such as lethargy, excessive drooling, or abdominal pain. If symptoms worsen or persist beyond 24 hours, seek veterinary care immediately.
While ringless honey mushrooms are typically safe for dogs, it is crucial to be aware of look-alike mushrooms that may be toxic. There are over 10,000 species of mushrooms in the United States, and accurately identifying mushrooms can be challenging. To positively identify a ringless honey mushroom, a spore print test is necessary, as observing features alone is not sufficient. This is because some look-alike mushrooms can be deadly or cause severe illness.
If your dog has ingested wild mushrooms, it is important to act quickly. Mushroom poisoning in dogs can be life-threatening, and even a single mushroom of certain species may contain enough toxin to be lethal. The mechanism of poisoning varies depending on the mushroom species, but the deadly Amanita species, for example, is absorbed by the stomach and then travels to the liver, causing liver failure. The toxins are then excreted by the kidneys, resulting in subsequent kidney failure.
Symptoms of mushroom poisoning in dogs can appear quickly, within 15-30 minutes after ingestion, or they may be delayed by up to 24 hours. Common clinical signs include vomiting, diarrhoea, lethargy, drooling, abdominal pain, tremors, and seizures. If you suspect your dog has ingested any type of wild mushroom, it is crucial to seek immediate veterinary care, even if no symptoms are apparent. Treatment may include activated charcoal, IV fluids, and supportive care.

Honey mushrooms have many lookalikes, some of which are deadly
Honey mushrooms are generally considered non-toxic to dogs, but they can cause mild gastrointestinal symptoms like vomiting, diarrhoea, and lethargy. However, it's important to note that honey mushrooms have many lookalikes, some of which are deadly. While the scientific name for the ringless honey mushroom is Desarmillaria caespitosa (formerly Armillaria tabescens), there are many other species of mushrooms that can easily be mistaken for honey mushrooms.
Honey mushrooms are known for their golden or yellow caps, but there are many other mushrooms with yellow caps that can be toxic. For example, the deadliest type of mushroom for dogs, Amanita, often has a yellow cap with white spots. Amanita mushrooms can cause liver failure and subsequent kidney failure in dogs, and just one mushroom may contain enough toxin to be lethal. Other toxic mushrooms that may be mistaken for honey mushrooms include those in the Galerina and Lepiota species, which can also be deadly.
To make identification even more challenging, the appearance of honey mushrooms can vary depending on their location and substrate. While they typically have golden or yellow caps, they can also appear brown. Honey mushrooms grow on dead or living tree roots, particularly fruit tree stumps and the dead ends of oak trees. They are most commonly found in the cooler regions of the United States and Canada, and they typically fruit in early fall for about one to two weeks.
Due to the potential for fatal mushroom poisoning, it is always best to treat any wild mushroom ingestion by a dog as a medical emergency. If you suspect your dog has ingested a wild mushroom, seek immediate veterinary care, even if they are not currently showing any symptoms.

Honey mushrooms are safe for humans to eat
Honey mushrooms are generally considered safe for human consumption. They are a great source of antioxidants, which help protect against chronic diseases and have been shown to have cancer-fighting properties. They also have blood sugar-lowering properties that could be therapeutic in treating several chronic conditions.
However, it is important to be aware of look-alike mushrooms that may be toxic. For example, deadly galerina, or Galerina marginata, is a toxic fungus that looks similar to the honey mushroom. It is slightly smaller, usually dark brown, and has a convex cap that flattens with maturity. Its stem is gradient, with an off-white shade at the top near the cap and a darker brown colour towards the bottom. To differentiate between the two, you can check the spore print: honey mushrooms will leave behind white spores, while deadly galerina will leave a rust-coloured brown spore print.
Honey mushrooms can also be difficult to identify and cook. They are found growing in temperate regions worldwide, often on dead wood, such as tree stumps or roots. They should have white spores and grow in one clump. Before consuming honey mushrooms, it is important to cook them thoroughly to ensure safety. Some people experience gastrointestinal allergies, so it is recommended to eat a small amount and wait 24 hours to observe any adverse reactions.

If ingestion is suspected, monitor closely and seek veterinary care if symptoms develop
Ringless honey mushrooms are generally considered non-toxic to dogs, but individual dogs may respond differently to ingestion. If you suspect your dog has ingested ringless honey mushrooms, it is important to monitor them closely for any signs of distress such as lethargy, excessive drooling, abdominal pain, vomiting, or diarrhea. These symptoms could indicate gastrointestinal issues, which can be severe and lead to dehydration and a decreased heart rate. In some cases, mushroom poisoning can also cause neurologic and hallucinogenic effects, resulting in stumbling, tremors, and even seizures.
If your dog is displaying any of these symptoms, seek veterinary care immediately. It is also important to note that even if your dog is not displaying any immediate signs of illness, mushroom poisoning can be fatal. Therefore, it is always best to consult a veterinarian as soon as possible after suspected ingestion. They may advise giving your dog activated charcoal, which can help to absorb any toxins in the stomach, and IV fluids to prevent dehydration.
To prevent accidental poisoning, it is important to supervise your dog during outdoor play and remove any unknown mushrooms from your yard or areas where your dog plays. It is also a good idea to educate yourself on toxic plant identification, including learning about the look-alike mushrooms that may be dangerous for your dog. Remember, even if a mushroom is identified as non-toxic, some dogs may still have individual sensitivities or reactions, so it is always best to monitor your dog closely and seek veterinary care if you have any concerns.
Additionally, while honey mushrooms are typically considered safe for human consumption, it is important to positively identify them before consuming them yourself or allowing your dog to eat them. This can be challenging, as there are many look-alike mushrooms, and even properly identified ringless honey mushrooms can cause acute gastrointestinal issues in some people. Always cook honey mushrooms before consumption, as raw honey fungus has been linked to dog deaths.
