Torn fibrecap Toxic?
Contains 333-1100x more muscarin than fly agaric; muscarin is heat-stable and not broken down by digestive enzymes
Onset of cholinergic poisoning symptoms occurs 15-60 minutes post-ingestion
Atropine is the recommended antidote for life-threatening cholinergic symptoms

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Induce vomiting only if the patient is conscious and ingestion occurred within the last 2 hours
- • Collect any remaining mushroom sample for accurate species identification
- • Avoid giving food or liquids that may speed up toxin absorption
Contact Vet Immediately
- • If ingestion of this species is confirmed, even if no symptoms have appeared yet
- • If any poisoning symptoms appear after wild mushroom exposure
- • If the patient experiences difficulty breathing, excessive salivation/bronchial secretions, or abnormal heart rate
Prevention
- • Never consume wild mushrooms unless positively identified as safe by a certified experienced mycologist
- • Restrict pet and livestock access to areas where this mushroom species is known to grow
- • Learn to distinguish this toxic species from common lookalike edible mushrooms before foraging
Treatment & Prognosis
- • Provide symptomatic supportive care including fluid therapy to correct hypovolemia
- • Administer atropine for life-threatening cholinergic symptoms until respiratory secretions stop
- • Continuously monitor vital signs (heart rate, respiratory rate, body temperature) until symptoms fully resolve
Professional Toxicology
• Excess muscarin stimulates peripheral cholinergic receptors, triggering over-secretion of exocrine glands and altered autonomic nerve function
• Muscarin is not degraded by digestive enzymes and is poorly absorbed in the gastrointestinal tract
• Muscarin cannot cross the blood-brain barrier, so central nervous system effects are limited
