Quick answer
Matsutake has a strong, spicy smell, often compared to cinnamon, and its stem tapers into the soil inside a sheath of white tissue below the ring, with no cup; the western destroying angel has no spicy smell and its bulbous base sits in a white, membranous cup. Matsutake caps and gills develop brown to orange-brown stains with age, while the destroying angel stays white.
Deadly lookalike
Unlike matsutake, 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.
