Pennsylvania, known for its vast and diverse landscape, is home to a variety of mushrooms. While many of these fungi are edible and safe to consume, there are some that are highly toxic and can be fatal if ingested. It’s crucial to be well-informed and cautious when foraging for wild mushrooms, as even experienced mushroom hunters can sometimes mistake a poisonous variety for a safe one. In this guide, we will discuss some of the most dangerous mushrooms found in Pennsylvania, their identifying characteristics, and the symptoms they can cause.
Amanita Family: The Death Cap and Destroying Angel
The Amanita family of mushrooms contains some of the most deadly species, including the Death Cap (Amanita phalloides) and Destroying Angel (Amanita virosa and Amanita bisporigera). These mushrooms contain the toxins amatoxin and phallotoxin, which can cause severe liver and kidney damage, leading to death in severe cases.
Identifying Characteristics: The Death Cap has a smooth, greenish-yellow cap and white gills, while the Destroying Angel has a pure white cap and gills. Both have a white, bulbous base with a ring-like structure around the stem.
Symptoms: Symptoms usually appear 6 to 24 hours after ingestion, beginning with severe abdominal pain, vomiting, and diarrhea, followed by a period of apparent recovery. However, this recovery is deceptive, as liver and kidney damage progresses and can lead to organ failure, coma, and death if left untreated.
Galerina Family: The Deadly Galerina
The Deadly Galerina (Galerina marginata) is a small, brown mushroom that grows on decaying wood. It contains the same toxins as the Amanita family, making it just as dangerous.
Identifying Characteristics: This mushroom has a small, brown, sticky cap with brown gills and a thin stem. It often grows in clusters.
Symptoms: The symptoms and progression of poisoning from the Deadly Galerina are similar to those of the Amanita family.
Gyromitra Family: The False Morel
The False Morel (Gyromitra esculenta) resembles the highly sought-after edible Morel mushroom. However, it contains gyromitrin, a toxin that can cause severe neurological symptoms.
Identifying Characteristics: False Morels have a wrinkled, brain-like cap with a reddish-brown color, while true Morels have a distinctive honeycomb pattern and are completely hollow inside.
Symptoms: Symptoms typically appear within 6 to 12 hours and can include headache, dizziness, gastrointestinal distress, and in severe cases, seizures, and coma.
Inocybe Family and Clitocybe Family: Muscarine Poisoners
Some mushrooms in the Inocybe and Clitocybe families contain the toxin muscarine, which can cause severe respiratory distress and other symptoms.
Identifying Characteristics: Inocybe mushrooms have small, brown, fibrous caps with brown gills, while Clitocybe mushrooms have a white, funnel-shaped cap with white gills.
Symptoms: Muscarine poisoning can cause symptoms such as excessive sweating, salivation, blurred vision, breathing difficulties, and a slow or irregular heartbeat. Onset of symptoms is usually rapid, occurring within 15 minutes to 2 hours after ingestion.
In summary, it is essential to exercise caution when foraging for wild mushrooms in Pennsylvania. The best way to avoid poisonous mushrooms is to learn from experts and consult reliable resources to accurately identify the fungi you come across. When in doubt, it’s always best to avoid consuming wild mushrooms.
