Assessment Notes

Taxonomic notes

Spores of this species are formed in sporocarps and isolated in the soil. Hyaline spores, yellow to light yellow; subglobous; (13-) 36 (-43) m; piriform, ovoid to irregular; 20-53 x 25-73 μm; with a subtitle hypha. A special characteristic of G. nanolumen is the irregular thickness of the laminated wall.


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

Apparently this species has been recorded only in North America (Hawaii-USA) and South America (Brazil).


Population and Trends

It is believed that with more studies in different habitats, this species will increase its occurrence number.
 

Population Trend:


Habitat and Ecology

The species was described from calcareous sand dunes in Hawaii and in Brazil it was recorded in areas of the Atlantic and Amazon rainforests.

Subtropical/Tropical Moist Lowland Forest

Threats

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

Housing & urban areasOther ecosystem modificationsHabitat shifting & alteration

Conservation Actions

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 associated hosts.

Site/area protectionResource & habitat protectionHabitat & natural process restoration

Research needed

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.
