Destroying Angel Mushroom (Amanita bisporigera): How to ID

• Cap: Cap 3-13 cm wide, smooth, white, sometimes with pale brown or cream tones.
• Gills: White, closely spaced, free or nearly free gills.
• Stem, ring and volva: Stem 6-14 cm, white; has a white, thin, membranous ring; base has an egg-shell-like, sac-like volva.
• Spore print: White.
• Where and when it grows: Mixed coniferous and deciduous forests, near oaks; fruits from summer to early autumn.
• Range in North America: Most common in eastern North America, rare in the west, ranging south to Mexico.

• young puffballs: Check the internal structure by slicing lengthwise: a young destroying angel reveals a differentiated cap/gill outline inside, while a puffball's interior is uniform.

Toxin: amatoxins (liver and kidney damage, delayed onset). Severity: can be fatal. Timing: Symptoms appear 5 to 24 hours after ingestion, by which time the toxins may already have been absorbed. A delayed start is the dangerous part: hours without symptoms do not mean the mushroom was harmless.

Call Poison Control at 1-800-222-1222 (U.S.) right away, or your local emergency number. Keep any leftover mushroom, a photo of it, and note when it was eaten. Do not wait for symptoms and do not try home remedies. This page does not give medical advice.

A clear photo of the whole mushroom, including the base dug out of the ground, the gills and a spore print, lets the app and a mycologist narrow down what it might be and flag features that match Eastern destroying angel. No photo, app or website can confirm that a wild mushroom is safe to eat. Use identification to know what to avoid, not what to cook.

Destroying angel is a name for several all-white, deadly Amanita species rather than one. Wikipedia lists Amanita virosa in Europe, Amanita bisporigera in eastern North America and Amanita ocreata in western North America; another European species, Amanita verna, is called the fool's mushroom. 'Angel of death' is another common search name for the same group.

They share the Amanita body plan: white free gills, a skirt-like ring on the stem, and a volva, a sac that wraps the whole mushroom like an egg when it is young and remains as a cup at the base.

Yes, destroying angels grow across much of the U.S. The Missouri Department of Conservation (MDC) calls Amanita bisporigera very common throughout Missouri and statewide, growing on the ground in mixed woods and in grass near trees from June to November. MDC gives the cap as 2 to 5 inches wide and the stalk as 3 to 8 inches long, and its guide notes poisoning cases among immigrants.

On the West Coast, Amanita ocreata was one of the two species behind California's 2025-26 outbreak, which CDPH counted at 50 cases and 4 deaths between November 2025 and May 2026.

They are different species in the same genus with the same poison. Both contain amatoxins, and Wikipedia says the two groups together account for the overwhelming majority of deaths from mushroom poisoning.

• Colour. Destroying angels are white all over. The death cap is usually pale green, yellowish or olive, although white forms exist.
• Range. In North America, destroying angels are native and widespread; the death cap is an introduced species concentrated on the coasts.
• Danger. The same. Wikipedia notes as little as half a destroying angel cap can be fatal, with symptoms starting 5 to 24 hours after eating.

Wikipedia names button mushrooms, meadow mushrooms and horse mushrooms as the edible species most often confused with destroying angels, and young specimens still inside their veil as puffball look-alikes. The checks:

• Gill colour. MDC separates the meadow mushroom by gills that are pink, then brown, and a brown spore print. Destroying angel gills stay white and print white.
• The base. Dig the whole mushroom out. A sac-like cup around the base means Amanita. MDC notes the meadow mushroom has no cup.
• The cut test for 'puffballs'. Holden Forests & Gardens: an edible puffball is completely white inside, while an Amanita egg cut top to bottom shows the outline of the developing mushroom.
• Location is not a clue. MDC finds destroying angels in grass near trees, the same places people find meadow mushrooms.

Many people do, if they reach hospital early. In California's 2025-26 outbreak, CDPH recorded 4 deaths among 50 cases, and at least 4 people needed liver transplants. Wikipedia puts modern mortality for death cap poisoning at around 10 to 15%.

What improves the odds is speed: going to hospital before symptoms appear and bringing the mushroom. Call Poison Control at 1-800-222-1222 (U.S.) now, before symptoms start.
