Aurantius Luminae, from Latin for orange and light, is a striking bioluminescent fungus noted for its vivid orange to deep crimson wavy caps and decurrent gills. Caps reach up to 15 cm height and 15-50 g weight, found in tropical rainforest understories. The stout, velvety stipe bears powdery white patches. Its blue-green bioluminescence (450-495 nm), localized in gill tissue, likely results from a luciferin-luciferase reaction aiding spore dispersal under low light. Taxonomically in the Irido Myco cluster, it thrives at 15-25°C, decomposing leaf litter and woody debris as a saprotroph. The mycelium permeates soil and substrate, supporting nutrient cycling and ecosystem dynamics. Luminescent gills attract nocturnal fauna to enhance spore dispersal and gene flow.
