Spores range from globose to subglobose, occasionally irregular. They have a size ranging from 90 to 110 µm. It presents a scar indicating the region of contact between spores and the saccular neck during spore synthesis.
Considering the common record of this species in different ecosystems and countries I suggest its classification as LC.
The species in known in 8 countries. Despite having only 4 occurrences in GBIF for Brazil, this species is very common in the country. Having registration from the South to the North of the country.
A very common species in several countries. In Brazil, this species has records from natural areas to contaminated with arsenic.
Population Trend: Improving
In Brazil, this species is found in different Brazilian biomes: Amazon rainforest, Cerrado, Atlantic rainforest, Caatinga and Pantanal.
As mandatory symbionts, the threats that affect its hosts (plants) will eventually affect the associated arbuscular mycorrhizal fungi. However, due to the registration of Acaulospora mellea in different environments, including contaminated ones, it may be an indication that this species is more resistant to human disturbances.
The development of necessary actions for the conservation of this species means a response in the search for the improvement of the environmental quality and reduction of the anthropic pressures on the plants and the soil.
Further studies on the ecology of fungi are needed, seeking to understand how mycorrhizal fungi relate to each other, to the host and to the environment.
