''Glutinoglossum'' is a genus of six species of earth-tongue fungi in the family Geoglossaceae. The widespread type species, ''G. glutinosum'', is commonly known as the "glutinous earth tongue". ''G. heptaseptatum'' is known only from the Czech Republic. Four additional species were described in 2015.〔 ==Taxonomy== |2=''Gl. exiguum'' }} |2=''Gl. americanum'' }} |2=''Gl. heptaseptatum'' }} |2=''Trichoglossum hirsutum'' }} |2=''Geoglossum difforme'' }} |2=''Sabuloglossum arenarium'' }} }} |caption=Cladogram showing phylogenetic relationships of ''Glutinoglossum'' and related species based on a four-gene dataset.〔 }} The genus was circumscribed in 2013 to contain the type species ''Glutinoglossum glutinosum'' (formerly known as ''Geoglossum glutinosum''), and a new species, ''G. heptaseptatum'', found in the Czech Republic. Molecular analysis showed that the two species form one of five well-defined clades in the Geoglossaceae. ''Sabuloglossum'' was another genus newly described as a result of this analysis. Although the ''Glutinoglossum'' species are not distinguishable by gross morphological features alone, they can be distinguished by their microscopic characteristics, and have an 8–10% DNA sequence dissimilarity in their internal transcribed spacer regions.〔 The generic name ''Glutinoglossum'' (derived from the Latin ''glutinosus'', meaning "glutinous") refers to the sticky fruit bodies.〔 ''G. glutinosum'' is commonly known as the "viscid black earth tongue".〔 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「Glutinoglossum」の詳細全文を読む スポンサード リンク
