Omphalotus olearius, the Jack O'Lantern, exists in three variants or three different species depending on your viewpoint: a European form typically associated with olive trees, an orangish eastern species associated with hardwoods, and a greenish-orange California species associated with oaks. All glow in the dark. The eastern variant, known as Omphalotus illudens, has often been mistaken for Chanterelles and the mistake makes itself apparent in one to three hours with the onset of gastric upset lasting anywhere from a few hours to a few days. Abdominal pain, headache, a sense of exhaustion, sleepiness, feeling cold, weakness and dizziness are common. Diarrhea and sweating are uncommon. Internal bleeding has been reported in some cases. Terpinoid compounds are the important toxins. Early researchers reported muscarine in Omphalotus species, but except in some European cases, there are usually no PSL symptoms characteristic of muscarinic poisoning.
