Luminosa Aurantium, named for its shining orange caps, is a bioluminescent fungus with irregular lobate fruiting bodies exhibiting vivid orange pigmentation at edges and ridges, fading to creamy white margins. Caps are wavy with coarse textures and granular outgrowths, borne on a robust, short stipe with orange highlights, reaching up to 10 cm tall. The hymenium shows decurrent lamellae. Bioluminescence occurs at 450-495 nm in basal/interstitial tissues via luciferin-luciferase activity. Found in tropical rainforest canopies, it exhibits phototropic growth. Taxonomically in the 'Arboreal Aurantica' cluster, likely Agaricales, it disperses wind-borne basidiospores across 50 species. It forms extensive mycelial networks in decaying wood, serving as a saprotrophic decomposer recycling lignocellulose. Stable yet rare, it thrives at 5-25°C, filling a specialized ecological niche.
