Spores of light orange brown to dark orange brown color, measuring from 100-160 µm. The spore wall, in the L3 layer, has thorn-shaped ornaments.Formerly called Glomus infrequens

Considering the common record of this species in different ecosystems and countries I suggest its classification as LC.

This species has a worldwide distribution, and it has been recorded
in at least 20 counties.

Although the species has only 44 occurrences distributed in 10 countries in the GBIF, with records for Brazil this number is possibly much higher.

In Brazil, this species is registered in different biomes, such as Amazon rainforest, Cerrado, Atlantic rainforest and Caatinga

All actions that pose a danger to natural environments will affect this and
other species of mycorrhizal fungi.

Conservation actions for this species include the creation and
maintenance of protected areas.

Further studies on the ecology, taxonomy and distribution of this species, may help to understand the effects of disturbances on the community of these fungi.
