Chicken of the woods vs jack-o'-lantern
- Toxic: Jack-o'-Lantern
Look under the orange: chicken of the woods has yellow pores and no stems. A jack-o'-lantern has sharp orange gills on separate stems.
Quick answer
Both have true gills, but the false chanterelle's thin, crowded gills fork again and again, and it grows singly or scattered on rotting conifer wood, needle duff or wood chips; the jack-o'-lantern's sharp gills do not fork repeatedly, and it grows in dense, fused clusters at the base of hardwoods. The flesh is soft and pale in the false chanterelle, orange throughout in the jack-o'-lantern.
Toxic lookalike
The jack-o'-lantern (Omphalotus illudens) is poisonous; the false chanterelle (Hygrophoropsis aurantiaca) is not recorded as a dangerous poison. The Bay Area Mycological Society names illudins M and S as the main toxins in Omphalotus and describes a rapid onset of serious gastrointestinal symptoms, sometimes lasting several days. Tom Volk records severe cramps, vomiting and diarrhea, and the Missouri Department of Conservation notes that it is not life-threatening to healthy adults. The University of British Columbia's Mushrooms Up! guide records that information on the false chanterelle's edibility conflicts, that some field guides report adverse reactions, and that only one case of gastrointestinal upset appeared in the poisoning records summarized by the North American Mycological Association.
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
Reports conflict. Some field guides record adverse reactions, but the University of British Columbia's Mushrooms Up! guide notes only one case of gastrointestinal upset in North American poisoning records. It is not among the dangerous species.
It is sometimes called one, but the name usually means Hygrophoropsis aurantiaca. The jack-o'-lantern is a separate, poisonous species in the genus Omphalotus.

Keep checking
This page states what field guides record. It is not advice to eat, taste or handle anything, and a photo cannot settle edibility. If someone has eaten a wild mushroom that may be toxic, call poison control (1-800-222-1222 in the US) right away, before symptoms start: the deadliest species act hours later.
