Glomus magnicaule differs from G. macrocarpum in having very wide subtending hyphae with pores occluded both by lateral wall thickening and a plug, and by having a thin inner wall (Hall, 1977).
We suggest this species to be categorized as insufficient data (DD).
This species is known in 8 countries.
There are about 6 records in 2 countries (GBIF), however, it can be found in other countries (6).
Population Trend: Uncertain
In Brazil, the species is found in the Amazon, Cerrado and Atlantic Forest.
In Brazil, this species can be found in Tropical rainforest, considered hotspot and forests have higher rates of deforestation.
Most records are in area with native vegetation of Brazil. The isolation of this fungus in controlled condition represents an advance for the conservation of this species.
Other areas should be studied in order to assess the distribution of this species.
