Aborted Entoloma

Entoloma abortivum

Also known as Shrimp of the Woods

Aborted entoloma produces two strikingly different fruiting forms, alternating between a standard gilled mushroom and an irregular, white, spongy mass. Research revealed that this bizarre aborted structure forms when the mycelium attacks and parasitizes developing honey mushroom fruiting bodies. Common across eastern North American hardwood forests, it frequently fruits in late summer and autumn near decaying logs, stumps, and leaf litter.

  4. Very high
Why interaction risk is low
Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
  • Cross-sectioning: Cut aborted specimens in half to observe the marbled white interior structure.
  • Habitat Scouting: Search around fallen hardwood logs where honey mushroom mycelium is active.
