Virginia is home to a rich variety of mushrooms, with over 200,000 species, many of which are toxic and can cause severe illness or death. The Death Cap, for example, is one of the deadliest mushrooms in the world and is commonly found in Virginia. Other poisonous mushrooms in the state include the Destroying Angel, Fly Agaric, Funeral Bells, Sulphur Tufts, and Violet-toothed Polypore. Due to the high number of toxic mushrooms and their resemblance to edible varieties, it is crucial to properly identify mushrooms before consuming them.

The Death Cap is one of the world's deadliest mushrooms and is found in Virginia
Virginia is home to a rich variety of mushrooms, thanks to its diverse landscapes, which range from the Blue Ridge Mountains to coastal plains. Unfortunately, while some of these mushrooms are edible, many are highly toxic and can cause severe illness or death.
One of the most deadly mushrooms in the world, the Death Cap, can be found in Virginia. The Death Cap is responsible for most mushroom-related fatalities worldwide and contains deadly compounds known as amatoxins, which cause severe liver damage. This mushroom is often mistaken by foragers for edible or hallucinogenic species. It is identifiable by its pale yellow, green, or white cap and a skirt-like ring around the upper stem. In Virginia, it is often found in symbiotic relationships with oak and beech trees, sometimes forming "fairy rings" in forests.
The Destroying Angel is another deadly member of the Amanita family, which is also found in Virginia. This mushroom is tall, slender, and pure white, with a smooth cap up to 4 inches wide and a skirt-like ring near the top of the stem. Like the Death Cap, it contains amatoxins, leading to symptoms like vomiting, diarrhea, and eventual organ failure.
It is important to note that many toxic mushrooms resemble edible ones, so expert identification is essential before foraging. Symptoms of mushroom poisoning may include nausea, vomiting, hallucinations, and organ failure, and can be delayed by hours or days. Always cook wild mushrooms before consuming them and never eat a mushroom you are not 100% sure is safe.

The Destroying Angel is another lethal species found in the state
The Destroying Angel is characterised by its tall, slender, pure white appearance, with a smooth cap up to 4 inches wide and a skirt-like ring near the top of the stem. It is often found in grassy areas, woodlands, or near trees. It is also known as Amanita bisporigera or A. virosa, and it is a species found in eastern North America.
The mushroom first appears in summer as a white "egg", which forms the base of the structure. As the mushroom grows, the cap becomes conical, and when it eventually opens, the surface of the cap is smooth. The entire mushroom is pure white, with white gills and a white stipe. The stem almost always has a skirt-like ring, and the gills are free, not attached to the stalk. The cap can be anywhere from 2 to 4.5 inches across, and the stipe is usually 3 to 8 inches long and about 0.25 to 0.75 inches thick.
The Destroying Angel is extremely toxic, containing amatoxins, which lead to symptoms such as vomiting, diarrhoea, and eventual organ failure. It is important to note that many toxic mushrooms resemble edible ones, so expert identification is crucial before foraging or consuming any wild mushrooms.

Sulphur Tufts are poisonous to humans, causing vomiting, diarrhoea, and sometimes death
Virginia is home to over 200,000 mushroom species, many of which are toxic and can cause severe illness or death. One such species is the Sulphur Tuft (Hypholoma fasciculare), a common fall mushroom with bright yellow colouring. This species is toxic and should never be consumed. Its bitterness serves as a warning sign, but this could be overlooked when cooked with other mushrooms. Sulphur Tufts contain the toxic steroids fasciculol E and fasciculol F, which are responsible for their toxicity.
Symptoms of Sulphur Tuft poisoning usually occur 5 to 10 hours after consumption, including nausea, vomiting, explosive diarrhoea, and excess protein in urine. Some individuals have also reported distorted sensory experiences, such as impaired vision and temporary paralysis. If you suspect that you or someone you know has consumed Sulphur Tufts, seek medical assistance immediately.
Sulphur Tufts are easily identifiable by their bright yellow colouring, which fades with age, and their bitter taste. They are commonly found in deciduous forests, especially in late summer and fall, growing in large clumps on stumps, dead roots, or rotting trunks of broadleaved trees.
It is crucial to be able to identify toxic mushrooms like Sulphur Tufts, especially as many toxic species closely mimic edible ones. Foraging for mushrooms can be dangerous, and expert identification is essential before consuming any wild mushrooms.

Fly Agaric contains muscarine and ibotenic acid, leading to hallucinations and nausea
Virginia is home to over 200,000 mushroom species, many of which are toxic and can cause severe illness or even death. The Death Cap and Destroying Angel, for instance, are two of the most deadly mushrooms in the world and can be found in Virginia.
One of the most common causes of mushroom poisoning in Virginia is the Fly Agaric, which contains muscarine, muscimol, and other toxic alkaloids. The Fly Agaric is a bright red or orange mushroom with a distinctive white-spotted cap and a white underside. It is often found in coniferous and deciduous forests, near spruce, birch, or pine trees.
Fly Agaric contains both muscarine and ibotenic acid, which are responsible for its hallucinogenic effects. Muscarine binds with muscarinic acetylcholine receptors, leading to the excitation of neurons. Ibotenic acid acts as an agonist of NMDA glutamate receptors and certain metabotropic glutamate receptors, which control neuronal activity. Ingesting Fly Agaric can cause nausea, vomiting, diarrhoea, excessive salivation, perspiration, and watering of the eyes. In rare cases, it can also lead to convulsions. While deaths from consuming Fly Agaric are uncommon, ingestion can result in severe discomfort and illness, which usually begins within a few hours of consumption. Recovery typically occurs within 12 hours.

Violet-toothed Polypore is toxic to humans and dangerous for dogs
Virginia is home to over 200,000 mushroom species, many of which are toxic. The Violet-toothed Polypore is one such toxic species found in the state. While I cannot confirm whether it is dangerous to dogs, I can provide some general information about toxic mushrooms and dogs.
The Violet-toothed Polypore is toxic to humans. This mushroom species is found in deciduous forests, particularly in late summer and fall. It is identifiable by its white stem with a bulbous base and a skirt-like ring around the upper stem. It is crucial to avoid this mushroom unless it has been identified by an expert, as misidentification is a leading cause of poisoning.
Mushrooms are most prevalent during the spring to fall months, especially after heavy rainfall. They can be found in wooded areas, lawns, and various habitats, and they can appear quickly, sometimes overnight. It is important to inspect your yard regularly to remove any mushrooms before letting your pets out, as dogs are particularly susceptible to mushroom toxicosis due to their eating habits and roaming tendencies.
If you suspect your dog has ingested a toxic mushroom, seek immediate veterinary advice or contact a poison control center for pets, such as ASPCA Poison Control or the Animal Poisons Helpline. A delay in treatment can be dangerous, and specific risks can be determined if the mushroom species is identified. Symptoms of mushroom poisoning in dogs can include gastroenteritis-type syndrome, severe life-threatening disease, and even death.
