Glutinoglossum heptaseptatum is a species of earth tongue fungus in the family Geoglossaceae.

Glutinoglossum heptaseptatum was described in 2013 in a paper by mycologists V. P. Hustad, A. N. Miller, T. M. Dentinger and P. F. Cannon published in Persoonia.

The genus was created for G. heptaseptatum and G. glutinosum, which were found to comprise one of five distinct clades within the Geoglossaceae.

The species have an 8–10% DNA sequence dissimilarity in their internal transcribed spacer regions.

The field also contained mosses, Festuca rubra, Agrostis capillaris and Cirsium palustre.
