Assessment Notes

Taxonomic notes

Scutellospora hawaiiensis, a species common in coastal sand dunes of Hawaii, is described. The pale orange-brown to red-brown spores have six walls; an outermost unit wall (1.2–2.0 μm thick) appressed to a laminated wall (0.8–2.2 μm), a coriaceous wall (2.8–4.8 μm), a new type of wall (the “notching wall”) (0.5–1.6 μm), whose broken edges consist of a series of rectangular and V-shaped notches, resembling a torn linen cloth, a coriaceous wall (2.0–3.3 μm) and a thick amorphous wall (3.0–4.0 μm, expanding up to 88 μn when crushed in acidic mountants).

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

There are about 7 records in 3 countries (GBIF)

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

Site/area 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.
