Luminifungus Noctilucens, from Latin for 'light-emitting fungus,' is a bioluminescent species in the Galactic Mycelium cluster, emitting blue-green light (470-530 nm). It features clustered, plerocystidous fruiting bodies 0-15 cm tall, with convex to funnel-shaped, translucent violet caps speckled with golden luminescent vesicles. Decurrent gills beneath are illuminated with a pore-like arrangement supporting spores. Pale violet, smooth stipes anchor it to tropical forest floors of decayed litter and wood. Bioluminescence arises from a luciferin-luciferase reaction in caps and gills to attract nocturnal dispersers. Taxonomically, it belongs to Mycenaceae, genus Luminifungus, order Agaricales, with 20 species. Spore dispersal combines passive wind and luminescence-attracted insects. Its extensive hyphal mat decomposes organic matter, sustaining tropical soil health and biodiversity. It thrives in cooler microclimates (10-20°C) as a specialized bioluminescent decomposer.
