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.〔"Family: Geoglossaceae."

The family Geoglossaceae ''sensu lato'' was previously defined with 6 genera and 48 species.〔 Early molecular evidence using ribosomal DNA〔〔〔 suggested that Geoglossaceae ''sensu lato'' was not a monophyletic group, and that the hyaline spored genera (e.g. ''Leotia'', ''Microglossum'', and ''Spathularia'') were not allied within the same clade as the darker-spored genera (''Geoglossum'' and ''Trichoglossum''). Schoch et al.,〔 using a six-gene phylogeny including ribosomal DNA and protein-coding genes, found support for the establishment of a new class (Geoglossomycetes), containing the genera ''Geoglossum'', ''Sarcoleotia'', and ''Trichoglossum''. Further molecular research resulted in the addition of ''Nothomitra'' (previously treated as a relative or synonym of ''Microglossum'') to the group in 2011.〔 ''Glutinoglossum'' was circumscribed in 2013 to contain the species formerly known as ''Geoglossum glutinosum'', and a new European species, ''G. heptaseptatum''.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geoglossaceae」の詳細全文を読む スポンサード リンク
