Luminosa Spectralis, from Latin 'luminosa' (luminous) and 'spectralis' (ghostly), is a bioluminescent fungus in the Iridescent Folia cluster. It has epigeous, foliose fruiting bodies 10-30 cm tall with broad, wavy caps exhibiting blue-violet iridescence (450-495 nm), fading to pink and orange on densely spaced, fine gill-like lamellae. The slender, semi-translucent stipe shows phototropic curvature. Its luciferin-luciferase system localized in lamellae produces steady blue-green glow, aiding nocturnal insect attraction for spore dispersal. Native to tropical rainforests, it decomposes lignocellulosic detritus at 15-30°C. Taxonomically in Mycenaceae, genus Luminosa, order Agaricales, it forms an extensive mycelial network vital for nutrient cycling and soil health. Spore dispersal is passive, relying on wind and bioluminescence to enhance reproduction.
