Death cap vs gem-studded puffball
- Deadly: Death Cap
Sliced top to bottom, a puffball is pure white with no structure. A death cap egg shows a cap, gills and stem.
Gem-studded puffball vs western destroying angel: the egg hides a cap and gills
Quick answer
A gem-studded puffball is uniform pure white inside, with no structure; an unopened western destroying angel egg shows the outline of a cap, gills and stem. The puffball's skin is covered in short cone-shaped spines that rub off and leave a net of scars, while the Amanita egg is smooth and white.
Deadly lookalike
The western destroying angel is deadly.
Unlike the gem-studded puffball, the western destroying angel (Amanita ocreata) is deadly poisonous and contains amatoxins, according to MykoWeb's California Fungi. In the CDC's report on the 2025 to 2026 northern California outbreak, people who ate it developed abdominal pain, nausea, vomiting and diarrhea 8 to 12 hours after the meal; across the 39 Amanita cases in that report, three people needed liver transplants and four died. Amatoxins are not destroyed by cooking.
If someone has eaten a wild mushroom and feels unwell, or may have eaten one of these, call poison control now: 1-800-222-1222 in the US. Do not wait for symptoms.

FAQ
Common questions
Where does the western destroying angel grow?
Under coast live oak and other oaks in California and along the Pacific coast, fruiting from late winter to spring.
Can you tell a puffball from an Amanita egg without cutting it?
Not reliably. Spines on the surface suggest a gem-studded puffball, but the inside is what separates them.
