Nothomitra is a genus of fungi in the earth tongue family Geoglossaceae.
The genus was first circumscribed by Dutch mycologist Rudolph Arnold Maas Geesteranus from specimens collected in Upper Austria in autumn 1964.
[3] The placement of Nothomitra within the class Geoglossomycetes has been confirmed using molecular phylogenetics.
[4] Nothomitra is only known from Europe and China, though extensive distribution data is lacking.
The conservation of Nothomitra has not formally been assessed on a global scale.
