Jack-O'-lantern mushroom - Omphalotus olearius - grain spawn


Luminescent mushroom for decoration. The jack-o'-lantern mushroom's fruiting body (its stem and cap) has an orange color. Its bioluminescence, a blue-green color, is only observable in low light conditions when the eye becomes dark-adapted. Not the entire mushroom glows, only the gills do so, this is also called "foxfire". 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. The thin cap is yellow to a deep orange and has a length of 6 to 10 cm. The young cap is curved and gets more and more bell-mouthed. The rim is often rolled up (to the gills) and the derma seems smooth. It's often accrued centrally. The stem can be 5 to 15 cm long, is orange to gingerbrown and is reduced to the basis.

It could be mistaken as an edible chanterelle mushroom, but like most glowing mushrooms, the Omphalotus olearius is deadly poisonous! It could be mistaken as an edible pleurotus, but like most glowing mushrooms, the Omphalotus nidiformis is deadly poisonous!
