Geoglossaceae is a
family of
fungi in the order
Geoglossales,
class Geoglossomycetes. These fungi are broadly known as
earth tongues. The
ascocarps of most species in the family Geoglossaceae are terrestrial and are generally small, dark in color, and club-shaped with a height of 2–8 cm. The
ascospores are typically light-brown to dark-brown and are often multiseptate. Other species of fungi have been known to parasitize ascocarps. The use of a compound microscope is needed for accurate identification.
