Luminomycota Noctura, named from Latin 'lumen' (light) and 'noctura' (night), is a rare bioluminescent fungus of tropical rainforest understories. Its fruiting bodies feature wavy, funnel-shaped caps (10–25 cm tall) with translucent stipes. Caps emit an iridescent blue glow with violet and magenta hues due to a cellular arrangement enhancing light diffusion. Bioluminescence occurs at 470–530 nm, producing pulsating cyan to greenish-blue light via a luciferin-luciferase reaction localized in gills and stipes, aiding nocturnal spore release. It thrives on decomposing woody substrates, acting as a lignocellulosic decomposer. Classified within Agaricales’ Basidiomycetes, in the 'Iridescent Folia' cluster of five luminescent species, spores are dispersed by basidiospores attracting nocturnal insects. Its dense mycelium promotes nutrient cycling, vital to tropical forest ecosystems.
