Omphalotus olearius
The jack-o'-lantern mushroom's fruiting body (its stem and cap) is an orange color. Its bioluminescence, a blue-green color, is only observable in low light conditions when the eye becomes dark-adapted. The whole mushroom doesn't glow — only the gills do so. This is due to an enzyme, called luciferase, acting upon a compound called luciferin, leading to the emission of light much as fireflies do when glowing. Wikipedia
