Armillaria mellea
Bioluminescent fungi emit a greenish light at a wavelength of 520–530 nm. The light emission is continuous and occurs only in living cells. No correlation of fungal bioluminescence with cell structure has been found. Bioluminescence may occur in both mycelia and fruit bodies, as in "Panellus stipticus" and "Omphalotus olearius", or only in mycelia and young rhizomorphs, as in "Armillaria mellea". In "Roridomyces roridus" luminescence occurs only in the spores, while in "Collybia tuberosa", it is only in the sclerotia.
