Its spores measure 140-285 × 145-330 µm in diameter, dark brown, formed separately in the soil from the sporiferous saccule. It presents ornamentation in the laminated layer (L2 of the spore wall), described as a single layer reticulum on several spines (0.5 µm high).
Due to the lack of adequate information to make a direct or indirect assessment of its risk of extinction, based on its distribution and / or population status, I would suggest that this species be categorized as insufficient data (DD).
The species in known in four countries.Despite being referred to other locations in Brazil (Amazon, Minas Gerais and Pernambuco), this is the first record of this species on this site for the country.
There are about 9 records of this species in GBIF. However, so far, this is the first record on the site for Brazil.
Population Trend: Uncertain
In Brazil, this species is registered in different biomes, such as Amazon rainforest, Atlantic rainforest and Caatinga (in addition to anthropized environments: Agrosystems, Pastures and Mining).
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 vegetation.
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.
