Radiomyces Incandescens, named from Latin for 'ray' and 'glowing,' is a bioluminescent fungal species in the Purpuracensis Spectrapinkus cluster. Its fruiting bodies are 10-30cm tall with convex to umbonate caps of translucent orange tissue and densely packed golden gills with cap margin striations. The slender fibrous stipe supports clusters of caps emitting green-to-yellow bioluminescence (510-570nm) via luciferin-luciferase localized on gills and caps, aiding spore dispersal in tropical cave low-light conditions. Thriving at 10-20°C on decomposed woody substrates, it belongs to family Mycenaceae, genus Radiomyces, order Agaricales. Wind-dispersed spores and luminescence may attract vectors or deter predators. Its mycelium decomposes wood, recycling nutrients and supporting cave ecosystem biodiversity and energy cycles.
