Mature spores are large, up to 400 µm, globose to subglobose, white to cream to yellow and have a “germinative” layer with numerous “warts” or “papillae” that form on the inner surface and are especially concentrated in the regions where the germ tubes are formed.
Due to the several records worldwide, we suggest this species to be categorized as Least Concern (LC).
This species has a high number os records (161) in GBIF. It has been found in Brazil (ocuurring in all regions), Canada, China, Cuba, India, Japan, Mexico, New Zealand, Poland, Syria, USA.
The species has been found in many surveys worldwide and there are no records of decreasing populations
Population Trend: Uncertain
The species has a worldwide distribution and in Brazil it has been found in natural and antropized areas in different biomes such as Amazon rainforest, Cerrado, Atlantic rainforest, Pampa, Caatinga and Pantanal.
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
Essa espécie é mantida em culturas na coleção Embrapa Mandioca e Fruticultura, localizado em Petrolina.
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.
