Luminomyces auroralis, named for its dawn-like bioluminescence, is a cluster-forming fungal species with fruiting bodies up to 15 cm tall. Caps vary from convex to wavy margins, textured with small wart-like deposits and a teal overlay contrasting vibrant orange-yellow luminescent patches near cap edges and gills. Gills are densely packed, adnate to slightly decurrent, aiding spore dispersal. The stout stipe has subtle longitudinal striations and a flared base. Bioluminescence, emitting 470-530 nm light via a luciferin-luciferase system, localizes in specialized hyphal cells on caps and gills, enhancing spore release in low light. Found in temperate forest canopies on decomposing wood, it is a saprotroph in the Mycenaceae family, order Agaricales. Its growth allows strategic spore dispersal, while extensive mycelium decomposes lignin and cellulose, supporting nutrient cycling. Rare but locally abundant at 10–20°C, it contributes to biodiversity and detrital webs.
