Luminosa Radiata, meaning 'radiant light,' is a bioluminescent fungus of the Aetherium Arborescens cluster, family Mycenaceae, genus Luminosa, order Agaricales. It features translucent, wavy caps with irregular lobed margins and gelatinous texture, bearing smooth, moist surfaces and thin gill-like structures emitting faint blue-green light (470-530 nm). The slender, semi-translucent stipe supports caps up to 10 cm and 15 g. Bioluminescence results from luciferin-luciferase reactions mainly in the cap and gills, aiding dim understory illumination. Found in tropical rainforests (15-30°C) on decomposing wood and leaf litter, it plays a key saprotrophic role in nutrient cycling. Spore dispersal occurs via wind-driven basidiospores from elevated fruiting bodies. Its extensive mycelium sustains forest health. Near threatened due to habitat specificity, it enriches tropical bioluminescent diversity with 50 congeneric species.
