Assessment Notes

Taxonomic notes

Also known as Rhizoglomus intraradices or Glomus intraradices. Its spores are cream to yellowish brown, sometimes with a green hue. The color is highly variable in these shades. Irregularly shaped, with many elliptical spores. The outermost layer of the spore is hyaline, mucilagenic.


Why suggested for a Global Red List Assessment?

Due to the several records worldwide, we suggest this species to be categorized as Least Concern (LC).


Geographic range

Rhizoglomus intraradices is one of the most intensely studied arbuscular mycorrhizal fungi. Thus, it has a high occurrence, with registration in several countries worldwide. This is the first record of the species for Brazil, however it is well mentioned in different places.


Population and Trends

The ease of multiplying this species allows a great number of experiments to be carried out and with that the knowledge about the species has increased. Studies have shown that R. intraradices is found in
many ecosystems and can support diverse environmental conditions.
. Glomus intraradices is one of the most intensely studied arbuscular mycorrhizal
fungi. It has been found in different countries and biomes, with a worldwide distribution.

Population Trend:


Habitat and Ecology

In Brazil, this species is registered in different biomes, such as Amazon rainforest, Cerrado, Atlantic rainforest, Caatinga and Pantanal

Subtropical/Tropical Dry ForestDry Savanna

Threats

Rhizophagus intraradices is present in anthropized environments, high rates of anthropogenic disturbances such as deforestation, can have an effect on the population of this species.

Housing & urban areasScale Unknown/UnrecordedUnintentional effects (species being assessed is not the target)

Conservation Actions

Rhizophagus intraradices is easy to propagate in trap culture in association with different host plants (leek, parsley, Bahia grass, sorghum, etc.) which can assist in species maintenance. However, to conserve the species in its natural environment it is necessary to preserve not only the fungus, but also the vegetation and the associated soil.
