Luminomycota Azurei, named from Latin for light and blue, is a bioluminescent fungus in the Galactic Mycelium cluster. Its convex to broadly umbonate cap (0-15 cm) is azure with luminescent pinkish warts and a velvety surface with an undulate margin. The closely spaced, decurrent gills emit a blue-green glow (450-495 nm). The robust, cylindrical stipe has bluish fibrillose scales. Bioluminescence arises from a luciferin-luciferase system in cap and gills, with orange-yellow phosphorescent patches on the mycelium. Native to tropical caves, it thrives in humid, shaded microhabitats (5-20°C), decomposing organic detritus. Classified in Mycoglowaceae, Agaricales, it supports nutrient cycling and biodiversity. Spore dispersal is wind-mediated via basidiospores. This rare troglobitic fungus is protected and vital in cave ecosystems.
