Neonothopanus nambi

Neonothopanus nambi is a poisonous and bioluminescent mushroom in the family Marasmiaceae.

[1][2] The genetic and molecular mechanisms underlying this species' bioluminescence were published in 2019, the first to be elucidated for a fungus.

[3] In 2020, genes from this fungus were used to create bioluminescent tobacco plants.

[4] Italian-Argentinian naturalist Carlo Luigi Spegazzini described the species in 1883 as Agaricus nambí in the subgenus Pleurotus, from material collected in December 1879 near Guarapí,[5] a locality in Yaguarón, Paraguarí Department, Paraguay.

[7] Ronald H. Petersen and Irmgard Krisai placed the fungus in the new genus Neonothopanus in 1999.
