List of bioluminescent fungi

Found largely in temperate and tropical climates, currently there are known more than 75 species of bioluminescent fungi, all of which are members of the order Agaricales (Basidiomycota) with one exceptional ascomycete belonging to the order Xylariales. All known bioluminescent Agaricales are mushroom-forming, white-spored agarics that belong to four distinct evolutionary lineages. The Omphalotus lineage (comprising the genera Omphalotus and Neonothopanus) contains 12 species, the Armillaria lineage has 10 known species, while the Mycenoid lineage (Mycena, Panellus, Prunulus, Roridomyces) has more than 50 species. The recently discovered Lucentipes lineage contains two species, Mycena lucentipes and Gerronema viridilucens, which belong to a family that has not yet been formally named.Armillaria mellea is the most widely distributed of the luminescent fungi, found across Asia, Europe, North America, and South Africa.

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.
