Rhizoglomus fasciculatum previously assigned as Glomus fasciculatum and Rhizophagus fasciculatus it has dextrinoid reaction of the laminate spore wall layer 2, which does not seem to occur in other species of the same genus (Błaszkowski et al., 2003).
Due to the several records worldwide, We suggest this species to be categorized as Least Concern (LC).
This fungus has a worldwide distribution.
A very common species in several countries. It has 176 data according to GBIF when searching Glomus fasciculatum and Rhizophagus fasciculatus.
Population Trend: Stable
This species occurs in different Brazilian biomes: Amazon, Atlantic Forest, Cerrado and Caatinga.
It does not appear to be threatened, as it is well distributed and used in experiments with different hosts.
This species is well multiplied in trap culture, which may help in the maintenance of this species in the future.
Other areas should be studied.
