Glomus fuegianum has clusters that are much more compact than in G. australe (Berkeley) Berch. Besides, the spores of G. fuegianum “tend to be elongated, their shape resulting from multual packing in the tight clusters”, as mentioned by Berch & Fortin (1983), while those of G. australe are globose (Goto; Maia, 2005).
We suggest this species to be categorized as Least Concern (LC).
This species is known in 7 countries.
There are about 22 records in 5 countries (GBIF).
Population Trend: Uncertain
In Brazil, the species is found in the Amazon, Atlantic Forest and Cerrado.
In Brazil, this species can be found in Tropical rainforest and Tropical Dry Forest, forests have higher rates of deforestation.
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.
