Bioluminescence in mushrooms is indeed caused by a chemical reaction involving the molecule luciferin and the enzyme luciferase. When luciferin reacts with oxygen, it emits light, which is what makes these mushrooms glow.
The reasons for bioluminescence in fungi are still under study, but current theories suggest it might attract insects to help with spore dispersal or serve as a defense mechanism. Another hypothesis is that the glow could help in reducing oxidative damage in the fungus. These explanations are speculative but are commonly accepted among researchers.
Some types of Bioluminescent Mushrooms:
- Armillaria mellea (Honey Mushroom): Armillaria mellea does exhibit bioluminescence, but it’s primarily the mycelium (the underground network of the fungus) that glows, not the fruiting body (the mushroom cap itself). The glow is typically faint and can be seen in decaying wood.
- Mycena chlorophos: Mycena chlorophos is indeed a bioluminescent mushroom found in tropical regions, including Japan and Brazil. The greenish glow is visible in the dark and is mostly seen in the gills and stem.
- Panellus stipticus (Bitter Oyster): Panellus stipticus is a known bioluminescent species found in North America, Europe, and Asia. The gills and mycelium emit a dim green light
- Omphalotus olearius (Jack-O’-Lantern Mushroom): Omphalotus olearius is correctly identified as a bioluminescent mushroom. Its gills emit a faint green light, though the mushroom itself is orange.
- Neonothopanus gardneri: Neonothopanus gardneri is one of the brightest bioluminescent mushrooms and is native to Brazil. It emits a vivid green light and is among the most striking examples of bioluminescent fungi.
