Spores pale yellow to butter yellow, globose to subglobose. The germ wall 1 comprises two hyaline layers ornamented with knotty processes.

Due to the lack of adequate information to make a direct or indirect assessment of its risk of extinction, based on its distribution and / or population status, I would suggest that this species be categorized as insufficient data (DD).

Although GBIF mentions the occurence of this species only in three countries, other records show that it occurs in many ecosystems worldwide. In Brazil it has been commonly found.

With the increase in actions that encourage taxonomic research, it is believed that the number of occurrences for this
species will increase during new surveys.

In Brazil, this species is registered in different biomes, such as Amazon
rainforest, Atlantic rainforest, Caatinga, and Cerrado, occurring in habitats, such as: natural, agrosystems, impacted areas and rupestrian fields.

As Brazilian biomes are being occupied at different scales and speeds by man, extensive areas of native vegetation are being devastated. Thus, the removal of vegetation and soil disturbance constitute a risk to the arbuscular mycorrhizal fungi community.

Conservation actions aimed at preserving the terrestrial ecosystem as a whole (soil + associated vegetation), consequently will have an effect on the conservation of these species.

Studies on arbuscular mycorrhizal fungi are still insufficient. Thus, there are many gaps on different aspects of ecology and distribution both for this species and for the group in general.
