Identification

Orange funnel-shaped caps in clusters on wood; sharp true gills running down the stem; flesh pale. A Mediterranean/southern species — known as a chanterelle lookalike for southern foragers.

Why it is dangerous

Contains illudin: severe vomiting, abdominal cramps and diarrhea within hours. Recoveries are typical but the course is harsh — and in the dark the gills faintly glow, hence the name.

How not to confuse it

Feature Chanterelle Jack-o'-lantern
