Acaulospora reducta has laminated wall spores (OWL2) with double ornamentation, consisting of large irregular depressions (7.8-5.2 × 7.8-17.9 µm) and a roughness consisting of small internal depressions (<1 µm) can be easily differentiated from other species of the genus Acaulospora ( Oehl et al., 2012 ).

We suggest this species to be categorized as Least Concern (LC).

This species is known in two countries.

Records are found in Brazil and Mexico.

In Brazil the species is found in the Amazon, Atlantic Forest, Caatinga and Cerrado.

This species can be found in Brazilian Tropical rainforest and Tropical Dry Forest. These forests currently have higher rates of deforestation, especially the Atlantic Forest, which is considered a hotspot.

Most records are in area with native vegetation of Brazil. 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.

None.
