Luminomyces Aureus, named from Latin ‘lumen’ (light) and ‘aureus’ (golden), is a bioluminescent fungal species in the Enigmatic Mycocluster. Its translucent, conical to broadly convex caps (10–25 cm tall) feature striate margins with orange to golden brown speckles. The hymenium has close gills radiating from a slender, semi-translucent stipe, both emitting blue-green light (470–530 nm) via a luciferin-luciferase system localized in gill tissue and stipe. Fruiting bodies densely cluster on decayed tropical wood. Saprotrophic, L. Aureus thrives at 5–25°C, decomposing organic matter and sustaining nutrient cycles. Spore dispersal is wind-assisted by raised gills. This species exemplifies a vital luminescent decomposer in tropical forest floors.
