Glomerosphaera Aurellum, from Latin 'glomero' (to form into a ball) and 'aurellum' (golden), is a bioluminescent fungal species in the Pyroglow Ignis cluster. It features convex to broadly umbonate caps with translucent, pale amber to golden surfaces scattered with minute orange glands. The adnate gills show fine serration and emit soft amber luminescence. The sturdy, semitranslucent stipe tapers at the base with bioluminescent vesicles. Fruiting bodies are 0–15 cm tall, weighing 5–25 g. Luminescence peaks at 470–530 nm via a luciferin-luciferase system, producing blue-green light suited to 10–20°C tropical rainforest canopies. Found on decaying bark and woody debris, it acts as a saprotrophic decomposer in Mycenaceae, Agaricales. Spores are forcibly ejected from gills, aiding dispersal. Its extensive mycelium breaks down wood polymers, supporting ecosystem nutrient cycling. Currently near threatened, conservation is crucial for tropical fungal biodiversity.
