Acaulospora tuberculata is similar in color to those of A. elegans, A. spinosa and A. foveata. The species is covered by tubercles (Janos; trappe, 1982).

We suggest this species to be categorized as Least Concern (LC) due to the several records worldwide.

The species is known in 11 countries.

A very common species in several countries. It has 14 data according to GBIF when searching Acaulospora tuberculata.

In Brazil, this fungus is found in forests under different biomes: Caatinga, Amazon, Atlantic Forest and Cerrado. In addition to anthropized environments (Agrosystems, Pastures and Mining).

In Brazil, Acaulospora tuberculata can be found in Tropical rainforest and Tropical Dry Forest, forests that have high rates of anthropic disturbance, such as deforestation.

Some records in Brazil are in unprotected areas. 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.
