AMF is a widely spread symbiosis forming associations with various hosts. These fungi play an important role in functioning and biodiversity of land ecosystems.

Since Spegazzini described the first AM fungi, Glomus fuegianum (as Endogone fuegiana) in 1887, the     number of species currently known have been increasing up to 46.

These species have been isolated from different environments such as: maritime dunes, cultivated soils, natural grasslands and forests.            

The aim of the present review is to show the AM fungal species known up to now from different ecosystems in Argentina.
