Luminifungus Auroralis, from Latin lumen (light) and aurora (dawn), is a rare bioluminescent fungus emitting a blue-green glow (400-480 nm). It features robust, funnel-shaped fruiting bodies (15-40 cm tall) with decurrent gills showing intricate wrinkles illuminated by internal bioluminescent tissues. The cap’s smooth surface transitions from deep violet to iridescent blue with amber highlights, indicating luciferin-luciferase activity beneath the cap skin and gills. The fibrous, scaled stipe supports clustered growth typical of the Galactic Mycelium clade. Thriving in temperate forests on decaying hardwood with moist, 5-25°C conditions, it belongs to Omphalotaceae (Agaricales). Spores disperse via wind from fertile gills. Its extensive mycelium enables saprotrophic nutrient cycling, vital for forest health. Fragile yet ecologically significant, it aids understanding fungal bioluminescence and temperate forest ecology.
