Luminarius Coloratus, named for its illuminating colored appearance, is a bioluminescent fungus with turquoise blue convex to broadly umbonate caps (10-25 cm) and radiant orange adnate to slightly decurrent gills and stipes. The sturdy, waxy cylindrical stipes support fruiting bodies in temperate forest understories. Emitting 470-530 nm blue-green light via a luciferin-luciferase system localized in gill and cap tissues, it likely attracts spore dispersers. Belonging to Pyroglowaceae (order Agaricales, Pyroglow Ignis cluster), it saprotrophically decomposes leaf litter and woody substrates at 10–20°C through extensive blue hyphal mats. Its gill morphology aids airborne spore dispersal. Protected status reflects its vital role in nutrient cycling and forest biodiversity.
