Assessment Notes

Taxonomic notes

The most striking characteristics of these species is the size of their spores, one of the largest in the phylum Glomeromycota reaching up to 812 µm. Features auxiliary cell with projections


Why suggested for a Global Red List Assessment?

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).


Geographic range

The species in known in 25 countries with the largest number of records for Brazil (11).


Population and Trends

Due to its large spores, this species, when present, is easier to be visualized. It is believed that with more research, the number of occurrence records for this species is even greater.

Population Trend: Improving


Habitat and Ecology

This species, in Brazil, has a good occurrence in humid tropical forests. In the dry tropical forest (Caatinga), it was more evident in natural areas and agrosystems.

Subtropical/Tropical Dry ForestSubtropical/Tropical Moist Lowland Forest

Threats

As a mandatory symbiote, this species is found associated with Brazilian tropical forest vegetation that are exposed to different types of anthropogenic disturbances such as high deforestation rates, for example.

Research needed

More research is needed on its distribution, taxonomy and ecology, such as: evaluating other areas, understanding if there is any relationship with the size of its spore and its habitat, etc.
