How to tell Panther cap from Grey veiled amanita
How they differ, how to recognize them and which is more dangerous — a mushroom comparison
Warning: Panther cap(Amanita pantherina)
POISONOUS
Eating it causes poisoning. Do not pick it unless you have identified it with certainty.
Higher concentrations of ibotenic acid and muscimol. Symptoms appear 30–90 minutes after eating and are more severe: deep hallucinations, possible coma. Get to a hospital immediately.
If you suspect poisoning, call an ambulance immediately: 112 (the European emergency number) or your local emergency number
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
The short answer
Panther cap and Grey veiled amanita look alike, so they're easy to mix up — but Panther cap is poisonous, while Grey veiled amanita is poisonous. The main visible difference: cap color: Panther cap — brown, grey, Grey veiled amanita — grey, violet, brown. The mushrooms also differ in the following features: cap shape, cap surface, taste. If you have even the slightest doubt, leave the mushroom be.

🔬 Morphology
Cap
Panther cap
Cap 5–12 cm across, spherical or bell-shaped when young, later flattened-convex. The surface is shiny, brown, gray-brown or olive-brown, dotted with small pure-white warts, usually spread fairly evenly; rain can wash them off.
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.
Hymenophore
Panther cap
Gills free, white, crowded. They don't change color when damaged — this sets them apart from a similar edible species (the blusher), whose flesh and gills turn pink.
Grey veiled amanita
Gilled hymenophore — gills white, free (not attached to the stem), moderately crowded. Spore print white.
Stem
Panther cap
Stem 6–12 cm tall, white, smooth, with a thin membranous ring in the upper part. At the base there is a bulb with remnants of the veil — not a free, sac-like volva, but one or more white woolly rings or a spiral above a narrow gutter on the bulb; this rimmed bulb distinguishes it from the blusher.
Grey veiled amanita
Stem 7-12 cm tall, 1-1.5 cm thick, cylindrical, with a pronounced bulbous swelling at the base. Color whitish to light gray, with violet or lilac tints, especially in the lower part. In the upper part — a white membranous ring with a violet tint. At the base — a volva forming a rim (not a sac like in the destroying angel, but a rim around the swelling).
Flesh
Panther cap
Flesh firm, white, does not turn pink when damaged (a critical feature that distinguishes it from the similar blusher). No distinctive taste. The toxins are spread evenly throughout the whole fruiting body.
Grey veiled amanita
Flesh white, with a violet or lilac tint in the lower part of the stem. When cut, it does not change color (unlike the blusher, which turns strongly pink). The smell is faint; in some populations it has a note of old potato, radish or a damp cellar.
Smell
Panther cap
Smell faint, neutral or slightly unpleasant — subtly radish-like or earthy. It is neither sharp nor repulsive, which makes it harder to sense the danger while foraging.
Grey veiled amanita
Faint; in some populations with a note of old potato or radish. Not diagnostic for safety.
