Luminifera Glaciata, a bioluminescent fungal species endemic to deep cave systems, features irregularly lobed, translucent gelatinous caps with ruffled margins and radiating lamellae. Its pale lavender to icy blue bioluminescence, emitting 420-490 nm light via a luciferin-luciferase system typical of Noctiluca Grove, concentrates at cap edges and lamellae. The stout, semi-translucent stipe supports 10-25 cm tall fruiting bodies weighing 50-150 g. Thriving at 5-20°C on nutrient-rich decomposing substrates, it belongs to Mycenaceae, genus Luminifera, order Agaricales. Spore dispersal is passive via cave air currents. As a vital saprotrophic decomposer, it sustains nutrient cycling in nutrient-limited caves. It is vulnerable due to climate change, highlighting conservation needs.
