Glutinoglossum glutinosum, commonly known as the viscid black earth tongue or the glutinous earthtongue, is a species of fungus in the family Geoglossaceae (the earth tongues).
 Widely distributed in the Northern Hemisphere, it has been found in northern Africa, Asia, Europe, and North America.
 Although previously thought to exist in Australasia, collections made from these locations have since been referred to new species.
 "G. glutinosum" is a saprophytic species that grows on soil in moss or in grassy areas.
 The smooth, nearly black, club-shaped fruitbodies grow to heights ranging from 1.5 to .
 The head is up to 0.7 cm long, and the stipes are sticky.
 Several other black earth tongue species are quite similar in external appearance, and many can be reliably distinguished only by examining differences in microscopic characteristics, such as spores, asci, and paraphyses.
 First described in 1796 as a species of "Geoglossum", the fungus has gone through several changes of genera in its taxonomic history.
 It was placed in its current genus, "Glutinoglossum", in 2013. Central Black Earth Region
