I really love to eat mushrooms but would never eat wild mushrooms that I had found somewhere and couldn't identity. I always wanted to go mushroom hunting with a Mycology group. I love to shoot them because they have such interesting shapes. But when I saw black mushrooms appearing in the back yard, dark, black, glossy, dangerous looking ones, I wanted to know what they were and still haven't found them.
There are a variety of mushrooms, divided into categories or groups. Each category causes different symptoms.
Group 1. CYCLOPEPTIDES: The first signs and symptoms may not develop for six to 24 hours, usually 10-14 hours after the ingestion. Symptoms begin with sharp abdominal pains, followed by violent vomiting and persistent diarrhea, often containing blood and mucous. In three to four days, the patient begins to worsen with symptoms of kidney and liver failure. Death is very possible.
Group 1A. ORELLANINE: Symptoms begin 36 hours to 11 days after ingestion. They include nausea, lack of appetite, headache and, most importantly, a severe burning thirst and kidney failure.
Group 2. IBOTENIC ACID-MUSCIMOL: A state resembling alcohol intoxication develops 30 to 60 minutes after ingestion. Confusion, muscle spasms, delirium and visual disturbances, which last for about four hours, develop following the intoxicated state. Vomiting usually does not occur. Drowsiness and sleep follow and recovery is usually rapid.
Group 3. MONOMETHYLHYDRAZINE: After six to eight hours, the patient experiences a feeling of fullness in the stomach followed by vomiting and watery diarrhea. Headache, fatigue, cramps and intense pain in the liver and stomach regions occur, followed by jaundice. Seizures occur in severe cases.
Group 4. MUSCARINE-HISTAMINE: Within 30 minutes to two hours after ingestion, symptoms include sweating, drooling, diarrhea, watery eyes, blurred vision, pinpoint pupils, decreased heart rate and blood pressure, and asthmatic breathing. (The sweating, drooling, diarrhea and watery eyes do NOT occur with other types of mushroom poisonings.)
Group 5. COPRINE: Symptoms will occur if this mushroom is eaten by a person who drinks alcohol within the next 5 days. Flushing of the face and neck, a metallic taste in the mouth, numbness of the hands and feet, palpitations, and an increased heart rate are the symptoms.
Group 6. PSILOCYBIN-PSILOCYN: These are the hallucinogenic mushrooms that alter consciousness. An intoxicated or hallucinogenic condition begins between 30 and 60 minutes after ingestion. The mood may be apprehensive (anxious) or pleasant. The person may experience compulsive movements and uncontrolled laughter. In children, a high temperature (102-106½ F) with seizures may develop.
Group 7. GASTROINTESTINAL: Within 30 to 90 minutes of ingestion, sudden severe vomiting and mild to severe diarrhea with abdominal cramps occurs. Symptoms generally last six hours. In children, this may lead to dehydration severe enough to require hospital treatment. via Myko Web
