Luminorgloria mysticus, named from Latin for light and glory, is a rare bioluminescent fungus with a cap up to 15 cm tall, exhibiting vibrant red to purple hues with yellow spots and a velutinous, moist surface. The cap’s convex, wavy margin surrounds closely spaced gills transitioning cream to pale orange as spores mature. The sturdy, slightly curved stipe bears fine fibrillose scales and displays phototropic growth. Bioluminescence occurs in the 450–495 nm blue-green spectrum, concentrated on gills and cap margin, via a unique luciferin-luciferase complex of the Irido Myco cluster. Endemic to tropical rainforest understories, it grows saprotrophically on decaying hardwood, aiding nutrient cycling. Taxonomically in Mycenaceae, genus Luminorgloria, order Agaricales, it disperses spores wind-assistively from lamellae. Its mycelium decomposes lignocellulose, underpinning ecosystem function. A protected species, L. mysticus exemplifies bioluminescent fungal ecological and evolutionary significance.
