SPECIES, AUTHORITY G. cycestris Phipps & Taylor 1996, p. 709, figs. 11-13.
LOCATION Fremouw Peak, Antarctica, near the Beardmore Glacier.
ORIG DESCRIPTION* Hyphae (1.6-) 5.3 (-7.4) µm in diameter, inter- and intracellular, occasionally sinuous, septa frequent, branching dichotomous; arbuscules with trunks (1.6-) 2.5 (-4.0) µm in diameter, branching secondary, ultimate branches less than 1 µm in diameter; vesicles (8-) 33 (-56) µm in diameter, lateral and terminal, occasional septum present at base.
COMMENTS* There are several features that are common to Gigasporites myriamyces and Glomites cycestris. Hyphae are inter- and intracellular, as in G. myriamyces, also with typically dichotomous branching and noncontinuous septa near branching points. Arbuscules of both types are not confined to any distinct region of the cortex, and are found in various stages of deterioration. Each cell contains a single arbuscule, although two arbuscules can branch off the same hypha into adjacent cells (fig. 11). [Further details in original paper.]

The epithet cycestris comes from its location within (Greek -estris) a cycad.
