Assessment Notes

Taxonomic notes

Current name is Dominikia aurea (Oehl. & Sieverding.) Blaszk., Chwat,
G.A.Silva & Oehl. This species forms sporocarps composed of spores that are quite close to each other. The interior of the sporocarp, consists of intertwined hyphae
with colors that vary from hyaline to straw yellow, whereas the spores are generally orange and ovoid, (36-) 55-65 x (30-) 45-52 μm.

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

TFirst described from Switzerland, this species was recorded in only a few
countries in Europe and also found in different biomes in Brazil.

Population and Trends

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

Habitat and Ecology

In Brazil, this species is registered in different biomes, Cerrado, Atlantic rainforest and Caatinga in natural, undisturbed areas.

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

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 the associated

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.
