Bioluminescence is the ability of living organisms such as animals, plants, fungi, bacteria etc to emit light. Bioluminescent mushroom are the fungal organisms that emit continuous, greenish light of wavelength 520-530 nm, that make them visible in the dark environments. However, emission of light is continuous from the living cells but no correlation of fungal bioluminescence and cell structure has been found. Recently, a novel strain of bioluminescent mushroom Roridomyces phyllostachydis has been discovered from the jungles of Meghalaya, North east India.
