Luminaea Noctum, named from Latin for light and night, exhibits striking nocturnal blue-green bioluminescence (420-490 nm) via a luciferin-luciferase system localized in crowded, orange-glowing gills and slender stipes with semi-transparent luminescent cores (10–25 cm, 5–25 g). The convex caps are smooth, translucent purple with iridescent spots. Thriving in tropical rainforest canopies on decayed hardwood at 10–20°C, L. Noctum plays a vital saprotrophic role in nutrient cycling. Belonging to Agaricales, Mycenaceae, genus Luminaea within the Galactic Mycelium cluster, it grows fruiting bodies to optimize spore dispersal, attracting nocturnal insects in a mutualistic ecosystem. Its extensive mycelial network decomposes lignocellulosic material, enhancing soil health. As a rare protected species, it exemplifies tropical biodiversity.
