Luminafungus Aurelius, from Latin 'lumina' (light) and 'aurelius' (golden), is a bioluminescent fungus of the Mycocluster (~200 rare species). It has medium-large fruiting bodies (5-30 cm), with convex to slightly funnel-shaped violet to deep purple caps, iridescent blue and gold hues, textured with concentric ridges and minute scales. The dense, adnate to decurrent gills emit warm amber light. Fibrillose, firm stipes taper at the base. Bioluminescence arises from a luciferin-luciferase system emitting blue-green light (470-530 nm), mainly from gills and stem base. Native to tropical rainforest canopies, it decomposes hardwood, aiding nutrient cycling. Taxonomically in Agaricales, genus Luminafungus, it disperses spores passively via wind in canopy strata. The extensive mycelium degrades lignocellulose, supporting forest ecology. Growth-based movement enables substrate niche expansion in its rare, temperature-sensitive habitat (5-25°C).
