This list of bioluminescent fungi has more than 125 known species found largely in temperate and tropical climates. They are members of the order Agaricales (Basidiomycota) with one possible 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 contains 12 species, the Armillaria lineage has 10 known species, while the Mycenoid lineage 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.
