Radiomyces Chrysodermis, named for its glowing golden skin, is a bioluminescent fungus of the Irido Myco cluster in Agaricales. It features coral-like, branching fruiting bodies with undulating, fan-shaped caps displaying dense gills. Caps are golden-orange with purple near the short to nearly absent stipe and a white tomentose margin. Fruiting bodies reach up to 15 cm and 5-25 g. Bioluminescence (420-490 nm) produces a cyan-green glow on cap margins and undersides, driven by luciferin-luciferase in hyphal tissues. It thrives in tropical rainforests (0-20°C), decomposing woody litter, contributing to nutrient cycling. It disperses spores by wind via fan-shaped gills and forms extensive mycelia on lignocellulosic substrates, vital as a saprotroph. Although rare, it is locally abundant in humid microhabitats.
