Amanita ocreata

🏷️ Description

Beware the beauty of Amanita ocreata, also known as the Death Angel, Western Destroying Angel, or Angel of Death! ☠️ This deadly mushroom lurks in the Pacific Northwest and California, hiding in oak woodlands from January to April. Often mistaken for edible mushrooms, it has caused severe poisonings in humans and animals alike.

⚠️ Foragers Beware! Only experts should collect Amanita species. "When in doubt, throw it out!"

🔎 Identification

• Cap: 1.97 to 5.91 inches (5 to 15 cm), convex to flat, white to ochre, sometimes with a brownish center. May have pinkish tones. No distinct warts but can have thin, appressed veil remnants.

• Gills: Crowded, white to cream, free or narrowly attached to the stem.

• Stem: 6–20 cm tall, white, with a bulbous base. Has a fragile, white ring that may collapse with age.

• Volva: A thin, white, sac-like structure at the base—often extensive, covering part of the stipe.

• Spore Print: White.

• Odor: Often mild when fresh, but older specimens may smell like bleach, chlorine, dead fish, or iodine.

• KOH Test: Flesh turns yellow when treated with potassium hydroxide.

🌍 Habitat & Distribution

Found under oak trees (Quercus agrifolia, Q. garryana) and sometimes near hazel.

Occurs from Washington to Baja California, possibly on Vancouver Island (unconfirmed).

👀 Look-Alikes

• Amanita velosa (lacks a ring, has a striate cap margin)

• Amanita lanei & A. calyptroderma (darker cap, lacks a ring)

• Volvopluteus gloiocephalus (pink spores, lacks a volva and ring)

• Agaricus & Puffballs (immature A. ocreata may look similar)

💀 Toxicity: A Silent Killer

Contains amatoxins that destroy the liver & kidneys—even a small bite can be fatal.

Symptoms appear 6–12 hours after ingestion:

• Stage 1: Abdominal pain, violent diarrhea, vomiting

• Stage 2: Temporary improvement (liver damage continues)

• Stage 3: Jaundice, seizures, coma, possible death in 6–16 days

🏥 Treatment

No antidote! Immediate hospitalization is required. Liver transplants may be the only life-saving option.
