Omphalotus olearius is a POISONOUS orange gilled mushroom that to an untrained eye appears similar to some chanterelles. It is notable for its bioluminescent properties. It is found in woodland areas in Europe, where it grows on decaying stumps, buried roots or at the base of hardwood trees. Omphalotus olearius and other Omphalotus species contains the toxin illudin S, and are poisonous to humans. While not lethal, consuming this mushroom leads to very severe cramps, vomiting, and diarrhea.

In September 2017, Omphalotus olearius, the Jack o’lantern mushroom, was discovered for the first time in the Netherlands; on an olive tree, imported from Spain.
