Luminaria Radiata, from Latin 'lumen' (light) and 'radiata' (radiating), is a bioluminescent fungus in the Ethereal Phosphorica cluster. It has a translucent, convex, yellow-orange cap fading to white near moist, gelatinous gills, which emit blue-green light (420-490 nm) along edges, likely from a luciferin-luciferase reaction aiding nocturnal spore dispersal. The robust, centrally attached stipe shifts from deep red-orange base to creamy white above. Fruiting bodies are 0-15 cm tall, weighing 5-25 g. Native to tropical rainforest understories, it thrives on decomposing wood in moist, shaded conditions. Taxonomically in Basidiomycota, possibly Mycenaceae genus Luminaria, it plays a saprophytic role, decomposing lignocellulosic matter and enriching soil, with an extensive mycelial network, adapted to 15-25°C.
