Luminomycota Fantastica, named for its bioluminescent fruit bodies, is a clustered, woody fungus 5-25 cm tall with broad, convex caps exhibiting warm orange to yellow lamellae. It forms arboreal clusters with robust, textured stipes partially fused to neighbors. Small nodules emit a cool blue-green bioluminescence (450-495 nm) via a luciferin-luciferase system, mainly on gill edges and mycelial mats, producing ethereal light characteristic of the Aetherium Arborescens cluster. Found in tropical rainforest understories at 5-20°C on decaying wood-rich substrates, L. Fantastica belongs to Mycenaceae, genus Luminomycota (Agaricales). Basidiospores disperse via gills in dense forests. Ecologically, it decomposes lignin and cellulose and likely attracts nocturnal insects to aid spore dispersal, contributing to rainforest nutrient cycling and biodiversity.
