Luminaria Shroomus, from Latin 'luminaria' (light) and 'shroomus' (fungi), is a bioluminescent fungus in the Luminispectra Chromagloria cluster. It features slender stipes supporting translucent, funnel-shaped caps with undulating margins and gills radiating from the apex, highlighted by luminescent ridges and pits with magenta to cyan gradients. Standing 10–25 cm tall, bioluminescence (450–495 nm) occurs at cap edges and gills in a pulsatile pattern, driven by a luciferin-luciferase system in specialized hyphal cells. Thriving in tropical cave systems (10–20°C), it decomposes organic matter, sustaining subterranean ecosystems. Taxonomically in Luminariaceae, Agaricales, it disperses basidiospores aided by light pulses attracting invertebrates. Its extensive mycelium breaks down lignin and cellulose, contributing to biodiversity and ecosystem function among ~10 related species.
