Gluminae Phosphoralis, named from Latin 'gluma' (husk) and 'phosphoralis' (light-bearing), is a bioluminescent fungal species within the Crepuscular Luminae cluster. It features broad, fan-shaped caps up to 15 cm tall, with magenta to violet hues and cyan luminous outlines accentuating radiating, deeply veined gills indicative of a lamellate hymenophore. The fleshy, semi-translucent stipes exhibit pulsating orange bioluminescence near cap and stipe junctions. Emitting light at 450-495 nm via a luciferin-luciferase reaction localized along cap margins and gill edges, its pulsatile glow likely attracts nocturnal spore-dispersing insects. Native to tropical forest floors (10-20°C), G. Phosphoralis thrives saprotrophically on decomposing organic matter, playing a key ecological role. Taxonomically, it belongs to order Agaricales, family Crepusculariaceae, genus Gluminae, among 20 related species. Its extensive mycelium supports nutrient cycling, integrating bioluminescence with ecosystem function in humid, shaded tropical habitats.
