Auroralumina Ignis, named for its fiery dawn-like glow, is a bioluminescent fungus with fruiting bodies 0-15 cm tall, bright orange to reddish-orange convex caps that become wavy at maturity, and densely spaced, paler orange gills. Its slender, translucent stipes bear fine hairs, anchoring clustered mushrooms to decaying wood in tropical cloud forests. Bioluminescence emits 470-530 nm blue-green light via a luciferin-luciferase system. Phototropic growth optimizes light exposure for wind dispersal of spores from gill basidia. Belonging to the Pyroglow Ignis cluster (Agaricales), it forms an extensive mycelial network decomposing organic matter. Thriving at 5-25°C in humid, shaded cloud forests, it acts as a saprotroph vital for nutrient cycling. The genus includes about 10 species, with Auroralumina Ignis common in its habitat.
