Also known as Rhizogglomus irregulares or Glomus irregularis, their spores generally form as dense clumps within the roots. They have variable color (hyaline to yellow) and 70-165 µm in diameter.
Considering the common record of this species in different ecosystems and countries I suggest its classification as LC.
GBIF mentions more than 350 occurrences of this species that has been recorded in many countries.
Possibly, changes in the species nomenclature make it difficult to record occurrences on this site. Based on this and in the absence of registration for Brazil, it is believed that the number for this species is even greater.
Population Trend: Improving
In Brazil, this species is registered in different biomes, such as Cerrado, Atlantic rainforest and Caatinga
As mandatory symbionts, arbuscular mycorrhizal fungi pass a part of the life cycle associated with a host (plant). Thus, the main threats related to these fungi are the loss of vegetation and soil disturbances
Soil microorganisms, especially arbuscular mycorrhizal fungi, receive little attention in the field of conservation biology, although they play a crucial role in the production of fundamental ecosystem services, such as fertility, soil formation and maintenance, nutrient cycling and plant community dynamics , among others. For the conservation of these fungi, in addition to the soil, it is also necessary to preserve the associated
In a future scenario, it is important to develop an information system that can predict the degree to which plants depend on mycorrhizal fungi and the effects of this association for both symbionts. In this perspective, understanding more about the evolutionary history and ecological aspects of these fungi, can help to understand the variation in functional attributes between species and even predict the result of interactions between the fungus and the host.
