Western Jack-O’-Lantern (Omphalotus olivascens) 🍄🎃

The Western Jack-O’-Lantern is a striking mushroom named for its bright pumpkin-orange color and its rare ability to glow in the dark. In very low light, once your eyes adjust, the gills on the underside emit a soft green bioluminescent glow, making it the most bioluminescent mushroom on the West Coast. While the exact purpose of this glow is still unknown, scientists speculate it may help attract animals that aid in spore dispersal. This mushroom is often mistaken for the edible chanterelle due to its similar appearance, but unlike chanterelles, the Western Jack-O’-Lantern is toxic and can cause severe gastrointestinal distress if consumed.
