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).
This fungus has 18 occurrences distributed in 8 countries. Although there is no occurrence for Brazil, Glomus microaggregatum is found in Rio de Janeiro, Alagoas, Belo Horizonte, Paraná, among other states.
Despite the species having 18 occurrences according to GBIF, with the records in Brazil this number tries to be much higher.
Population Trend: Improving
In Brazil, this species is registered in different biomes, such as Amazon rainforest, Cerrado, Atlantic rainforest and Caatinga
Although Glomus microaggregatum is present in anthropized environments; high rates of anthropogenic disturbances, such as deforestation, can affect the population of this species.
Soil microorganisms, especially arbuscular mycorrhizal fungi, receive little attention in the field of conservation biology, although they play a crucial role in the production of fundamental ecosystem services, such as fertility, soil formation and maintenance, nutrient cycling and plant community dynamics , among others. For the conservation of these fungi, in addition to the soil, it is also necessary to preserve the associated vegetation.
Other areas should be studied to assess the distribution of this species. In addition to a greater understanding of the effects of human disturbances on the species.
