Flavolux Lucentis, named from Latin 'flavus' (yellow) and 'lux' (light), is a bioluminescent fungus with vibrant yellow-orange, wavy overlapping caps showing violet undertones. Its fruiting body stands 10-25 cm tall, featuring pale lilac to cream lamellar gills beneath. The robust stipe tapers from yellow base to lavender apex, reflecting specialized pigment deposition. Bioluminescence occurs at 470-530 nm, likely via a luciferin-luciferase system adapted to temperate forest floors (10-20°C), with oxidative reactions in cap tissues attracting nocturnal spore dispersers. Taxonomically in an unresolved Irido Myco genus of 10 species, it saprotrophically decays leaf litter and woody debris, aiding nutrient cycling. Passive spore release from gills is optimized by upward growth. Its extensive mycelium forms networks supporting soil biodiversity. Listed as vulnerable, it exemplifies ecological specialization and bioluminescent adaptation in temperate fungi.
