Destroying angel vs shrimp of the woods: white lumps on the forest floor

Quick answer

The aborted form of shrimp of the woods is solid inside, white with pinkish marbled streaks and no mushroom outline; a young destroying angel, sliced top to bottom, shows the outline of a cap, gills and stem inside a white sac. The outside differs too: smooth and egg-shaped for the Amanita, lumpy and irregular for shrimp of the woods, which often grows beside honey mushrooms.

Deadly lookalike

The destroying angel is deadly.

Unlike shrimp of the woods, the destroying angel (Amanita bisporigera) contains amatoxins. The Missouri Department of Conservation records that symptoms often do not appear until 6 to 24 hours after eating, starting with vomiting, diarrhea and cramps, followed by kidney or liver dysfunction that can lead to death. The CDC explains that amatoxins halt protein production in cells, and that they are heat stable and not inactivated 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

What is shrimp of the woods?

The lumpy, aborted form of Entoloma abortivum, which grows near honey mushrooms. Research by Czederpiltz, Volk and Burdsall (2001) suggests the Entoloma attacks the honey mushroom, reversing the older view.

Can shrimp of the woods look like a destroying angel?

Yes. Both can appear as whitish lumps on the forest floor in late summer and fall. A lengthwise cut separates them.
