Mushrooms that glow in the dark are called bioluminescent fungi. There are over 70 species of bioluminescent mushrooms, with some estimates placing the number at over 100. Bioluminescence in mushrooms occurs due to a chemical reaction between oxyluciferin molecules, an enzyme called luciferase, and oxygen—the same reaction that makes fireflies glow. Mushrooms use this light to attract insects that will help spread their spores. This phenomenon is called foxfire and occurs mostly in fungi growing on decaying wood.

What You'll Learn
The phenomenon of glowing mushrooms is called foxfire
The light emitted by these mushrooms is the result of a chemical reaction between oxyluciferin molecules, an enzyme called luciferase, and oxygen—the same chemical reaction that causes fireflies to glow. This chemical reaction is a two-stage mechanism. In the first stage, a light-emitting substance called luciferin is reduced by a soluble reductase enzyme at the expense of NAD(P)H. In the second stage, the reduced luciferin is oxidized by an insoluble luciferase, releasing energy in the form of bluish-green light.
The purpose of this bioluminescence is not yet fully understood. One theory suggests that the light attracts insects that can help spread the mushroom's spores. Another theory proposes that the light acts as a signal, although it is unclear what the signal could mean or who it is intended for.
Some of the most well-known glowing mushrooms include the jack-o'-lantern, which is found in Europe, South Africa, and eastern North America, and the Panellus stipticus, which is one of the brightest-glowing bioluminescent mushrooms on Earth.

There are over 70 species of glowing mushrooms
Glowing mushrooms, or bioluminescent mushrooms, are a fascinating occurrence in nature. There are indeed over 70 species of mushrooms that can glow in the dark, with some sources stating there are currently at least 71 species, while others list over 125 known species. This phenomenon, known as bioluminescence, is the result of a chemical reaction involving luciferase, luciferin, and oxygen—a similar process to what makes fireflies glow.
The majority of these glowing mushrooms belong to the Mycena genus, also known as bonnet mushrooms. Some well-known examples of bioluminescent mushrooms include the jack-o'-lantern, which grows throughout Europe and parts of South Africa, and its Eastern counterpart, Omphalotus illudens, found in eastern North America. Both resemble chanterelles in their fiery orange colour and are poisonous. Another bright mushroom is Panellus stipticus, which is found in certain parts of North America and transforms from a dull yellow-beige during the day to a dazzling display at night.
The purpose of bioluminescence in mushrooms has been a subject of scientific inquiry. One theory suggests that the light attracts insects that can help disperse their spores, acting as a spore-dispersal strategy. This is similar to how fireflies use their light to attract mates. Mushrooms that grow in dense forests with little wind may benefit from attracting carriers that can spread their spores to new locations. Additionally, the light emission may serve as a signal to attract attention, similar to a lighthouse.
The biochemical mechanisms underlying fungal bioluminescence are not yet fully understood. However, researchers have made progress by preparing bioluminescent, cell-free extracts to study the in vitro requirements. Experimental data suggest a two-stage mechanism involving the reduction of luciferin by a reductase enzyme and its subsequent oxidation by luciferase, resulting in the release of energy as bluish-green light. Conditions like pH, light, and temperature influence bioluminescence, indicating a connection between metabolic activity and fungal bioluminescence.

Glowing mushrooms are bioluminescent
Glowing mushrooms, or bioluminescent mushrooms, are a fascinating occurrence in nature. This phenomenon is known as bioluminescence, the ability of living organisms to emit light. Out of 120,000 known species of fungi, about 100 are bioluminescent, with over 125 known species found in temperate and tropical climates. These glowing mushrooms captivate both scientists and enthusiasts alike, leading to ongoing research and exploration.
The light emitted by bioluminescent mushrooms typically appears as a constant greenish-blue hue, with the intensity of the glow varying among different species. The Panellus stipticus, for example, is one of the brightest bioluminescent mushrooms, transforming from a dull yellow-beige during the day to a dazzling display at night. Other notable bioluminescent mushrooms include the jack-o'-lantern, Omphalotus illudens, and various species within the Mycena and Roridomyces genera.
The biochemical mechanism behind fungal bioluminescence involves a two-stage process. Firstly, a light-emitting substance called "luciferin" is reduced by a reductase enzyme, with the energy required coming from NAD(P)H. In the second stage, the reduced luciferin is oxidized by an insoluble enzyme called "luciferase," resulting in the release of energy in the form of light. This is similar to the process that gives fireflies their glow.
The purpose of bioluminescence in mushrooms is not yet fully understood, but researchers propose that it serves as a spore-dispersal strategy. By emitting light, mushrooms may attract insects that will pick up and disperse their spores. This hypothesis is supported by the fact that most bioluminescent mushrooms are found in dense forest environments where wind dispersal is limited. The light from the mushrooms attracts insects that act as carriers, spreading the spores to new locations.
The glow of bioluminescent mushrooms follows a circadian rhythm, with increased brightness at night and dimmer light during the day. This cycle is influenced by factors such as pH, light, and temperature, indicating a link between metabolic activity and fungal bioluminescence. The discovery and exploration of glowing mushrooms continue to fascinate and provide insights into the mysteries of nature.

Glowing mushrooms are found in dense forests
Glowing mushrooms, or bioluminescent mushrooms, are a fascinating occurrence in nature. They are often found in dense forests, where their mysterious glow can create an enchanting atmosphere. These mushrooms are not just a whimsical sight, but they also serve a crucial ecological purpose.
Bioluminescent mushrooms are known to belong to the Mycena genus, commonly called bonnet mushrooms. They are found in various parts of the world, including the forests of Meghalaya in India, tropical regions worldwide, and forested hardwood areas in eastern North America. The phenomenon of bioluminescence in mushrooms is not limited to one or two species, but there are at least 71 known species of glowing fungi, with more being discovered and studied over time.
The light emitted by these mushrooms is the result of a chemical reaction involving luciferase and oxygen, similar to the process that makes fireflies glow. This reaction also produces a substance called "luciferin," which contributes to the mushrooms' ability to emit light. The light is typically a greenish-blue color, and the intensity of the glow can vary depending on factors such as temperature and their circadian rhythms.
The purpose of the mushrooms' glow is thought to be related to spore dispersal. In dense forests, the lack of wind can hinder spore dispersal, so the mushrooms use their light to attract insects and other arthropods. These creatures are drawn to the light and inadvertently help spread the spores to new locations, aiding in the mushrooms' survival and propagation.
Some notable examples of glowing mushrooms include the jack-o'-lantern (Omphalotus illudens), found in eastern North America; the luminous porecap (Filoboletus manipularis), found in tropical regions; and the Panellus stipticus, found in Australia, Asia, Europe, and North America. These mushrooms provide a captivating display of nature's ingenuity, showcasing the unique ways in which organisms adapt and thrive in their environments.

Glowing mushrooms are part of the Mycena, Omphalotus, and Roridomyces genera
Glowing mushrooms, or bioluminescent mushrooms, are a fascinating occurrence in nature. They are often found in dense forests, sprouting on decaying wood, and are known to belong to specific genera. The phenomenon of bioluminescence in mushrooms is not fully understood, but it is believed to be linked to spore dispersal. By emitting light, these fungi attract insects that can help spread their spores over long distances. This hypothesis is supported by the fact that most glowing mushrooms exhibit a 24-hour cycle, glowing more intensely at night when it is most effective in attracting insects.
Among the diverse world of fungi, glowing mushrooms primarily belong to three genera: Mycena, Omphalotus, and Roridomyces. The Mycena genus, also known as bonnet mushrooms, includes Mycena singeri, a rare species found in the lowland forests of South America. This mushroom has umbrella-shaped caps and emits a lovely green glow from its stipe and gills. The Mycena genus is quite diverse, with over 50 known bioluminescent species.
The Omphalotus genus, on the other hand, is well-known for its jack-o'-lantern mushrooms. These mushrooms have a fiery orange colour and are found in Europe, parts of South Africa, and eastern North America. They grow on decaying wood and are known to be poisonous. The Omphalotus lineage includes 12 species, some of which are the most widely distributed luminescent fungi, found across multiple continents.
The Roridomyces genus is a more recent discovery in the world of glowing mushrooms. A new species, Roridomyces phyllostachydis, was found in India's Meghalaya state, specifically in the West Jaintia Hills District. Members of this genus are described as very fragile and thrive in moist and humid conditions. They are known to grow on bamboo substrates, with only their stalks emitting light.
While less common, it is worth mentioning that other genera, such as Panellus and Armillaria, also contain bioluminescent species. The Panellus genus includes Panellus stipticus, one of the brightest-glowing mushrooms, found in various parts of the world. Armillaria includes the honey mushrooms, with the lemon honeycap (Armillaria limonea) emitting light from its gills.
