Faerie Lights: Bioluminescent Oyster Mushrooms

Bioluminescent Oyster Mushrooms by Jeff Baurs

It’s not every day that I learn something new about Michigan, but the fact that Michigan has mushrooms that produce their own illumination is a new one to me!! PlantSnap explains that Bitter Oyster Mushrooms (Panellus stipticus) are one of over 80 species of bioluminescent mushrooms:

The mushrooms use a class of molecules called luciferins, which paired with an enzyme and oxygen, release light. Panellus stipticus (also known as the bitter oyster) is one of the brightest-glowing examples of bioluminescent fungi. It is found throughout Asia, Australia, Europe, and North America. These flat mushrooms grow on tree branches creating a mesmerizing effect as soon as the sun goes down. Foragers are able to find this variety growing around birch, oak, and beech trees.

The luciferins found in bioluminescent mushrooms are the same compound found in fireflies and underwater creatures.

They recommend that the best way to find them is by identifying them in the daytime, and you can head over to It’s Nature for a look at the bitter oyster mushroom.
