Radiolaris Pulchravesicor, named from Latin meaning 'radiant beautiful bladder,' is a bioluminescent fungal species native to tropical forest floors. It features densely clustered fruiting bodies with convex to funnel-shaped vivid purple caps marked by golden-yellow splotches. The pale yellow, closely spaced lamellae and stout, textured, mottled stipes emit blue-green bioluminescence (420-490 nm) via a unique luciferin-luciferase reaction. Fruiting bodies range 0–15 cm in height, weighing 5–25 g. Found on decaying hardwood in humid, shaded habitats, it decomposes lignocellulosic material, aiding nutrient cycling. Taxonomically in the Enigmatic Mycocluster, it disperses spores wind-assisted from lamellae. Endangered by habitat loss, conservation is vital to preserve its ecological and luminous functions.
