When seen under a microscope, spores of Claroideoglomus etunicatum may easily be confused with others spores of Glomus and Claroideoglomus, produce yellow-coloured spores of a more or less overlapping range of their size. However, Claroideoglomus has hypha funnel- to bird-bill-shaped, with and walls that are > 2.5 times wider at the spore base than some distance from the base, the wall of spores of C. etunicatum is 2-layered, that of C. claroideum consists of four layers (Błaszkowski, 2003)
We suggest this species to be categorized as Least Concern (LC) due to the several records worldwide.
Claroideoglomus etunicatum to be one of the most commonly occurring arbuscular fungi in the world.
A very common species in several countries. It has 480 data according to GBIF when searching Glomus etunicatum and Claroideoglomus etunicatum.
Population Trend: Stable
This species occurs in different Brazilian biomes: Amazon, Atlantic Forest, Cerrado, Caatinga, Pampa and Pantanal.
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 controlled condition, which may help in the maintenance of this species in the future.
Other areas should be studied.
