How to tell False death cap from Grey veiled amanita

How they differ, how to recognize them and which is more dangerous — a mushroom comparison

Warning: Grey veiled amanita(Amanita porphyria)

POISONOUS

Eating it causes poisoning. Do not pick it unless you have identified it with certainty.

It contains ibotenic acid and muscimol — neurotoxins acting on GABA-A and glutamate receptors in the central nervous system. Symptoms appear 30 min - 2 h after eating: disorientation, hallucinations, euphoria or anxiety, muscle spasms (ataxia), nausea, vomiting, tachycardia, mydriasis (dilated pupils), and in severe cases — seizures, delirium, coma. Lasts 6-12 hours, sometimes up to a full day. Deaths are rare (unlike the deadly destroying angel and death cap), but the poisonings are severe and require hospitalization.

What to do if you suspect poisoning: call an ambulance immediately. Gastric lavage, activated charcoal (repeated doses). IV fluid therapy, monitoring. For seizures — benzodiazepines (diazepam). Do NOT use atropine — it is contraindicated in this type of poisoning (there is no muscarine here). Treatment lasts 1-3 days, usually followed by full recovery.

Prevention: no mushroom with a ring + a volva goes into the basket. Skip any gray-purple, violet or lilac gilled mushroom under pines and spruces.

If you suspect poisoning, call an ambulance immediately: 112 (the European emergency number) or your local emergency number

🔬 Morphology

Cap

Grey veiled amanita

Cap 5-10 cm across, hemispherical in young mushrooms, becoming convex-flat with age. Color gray-purple, lilac-brown, with a violet tinge, darker in the center. Surface smooth, slightly slimy in wet weather, with thin grayish membranous veil remnants (not white and fluffy, as on the panther cap). The cap margin is smooth, without grooves.

False death cap

Cap 5-10 cm across, hemispherical in young mushrooms, becoming convex-flat with age. Color pale yellow, lemon-citrine, creamy yellow, slightly darker in the center.

The cap margin is smooth.

Hymenophore

Grey veiled amanita

Gilled hymenophore — gills white, free (not attached to the stem), moderately crowded. Spore print white.
