Luminescens Mycela, from Latin 'luminescens' (glowing) and 'mycela' (mycelium), is a distinct species in the Luminous Terra cluster of bioluminescent fungi. It features a convex to umbonate cap (15-40 cm) with a smooth iridescent surface showing violet, pale blue, and fuchsia speckles. The underside has tightly spaced gills emitting a warm yellow-green glow (470-530 nm) via a luciferin-luciferase system. The long, slender, translucent stipe has sparse luminescent granules. It exhibits slow, substrate-adaptive growth and thrives in cool (10-20°C), humid cave microhabitats on decaying wood. Primarily saprotrophic, it aids nutrient cycling. Taxonomically, it belongs to Basidiomycota, Agaricales, Mycenaceae, genus Luminescens. Elevated fruiting bodies disperse spores by wind in caves. Its extensive subterranean mycelium supports stable populations among ten known cluster species.
