Sphaerostilbe repens

Sphaerostilbe repens is a species of fungus in the family Hypocreaceae. It is a bioluminescent fungus, meaning it has the ability to produce and emit light. This species is found in tropical and subtropical regions around the world.

Taxonomy

The species was first described scientifically by mycologist Miles Joseph Berkeley in 1856. The genus name Sphaerostilbe is derived from the Greek words sphaira (sphere) and stilbe (brightness), referring to the round, bright fruit bodies of the fungus. The species name repens is a Latin word meaning creeping, which describes the growth habit of the fungus.

Description

Sphaerostilbe repens is characterized by its small, round fruit bodies that are typically less than 1 cm in diameter. These fruit bodies are initially white, but become pinkish or reddish with age. The fungus produces a white mycelium that creeps along the surface of the substrate, giving rise to the species name repens.

Bioluminescence

Like other species in the family Hypocreaceae, Sphaerostilbe repens is bioluminescent. The fungus emits a soft, greenish light, which is most visible in the dark. The light is produced by a chemical reaction involving the compound luciferin and the enzyme luciferase. This phenomenon is known as bioluminescence, and is found in a variety of organisms, including some bacteria, insects, and marine animals.

Habitat and distribution

Sphaerostilbe repens is found in tropical and subtropical regions around the world. It is commonly found on decaying wood and other organic material. The fungus plays an important role in ecosystems by helping to break down and recycle organic matter.
