Assessment Notes


This is a widespread species which appears to be quite common. Any population declines are not likely to be steep enough to trigger a threatened category. It is therefore assessed as Least Concern.

Taxonomic notes

Why suggested for a Global Red List Assessment?

This is an ectomycorrhizal species that grows in nutrient poor sandy soil. The environment where it has been registered are suffering deforestation, mining and real estate speculation.

Geographic range

Occurs in white sand forests along the Guyana Shield, including Brazilian Amazon, Venezuela, Colombia, Guyana and French Guiana, and also on restinga vegetation in the Atlantic Rainforest in Northeast and South of Brazil.

Population and Trends

This species only occurs on specific vegetation types, and is only visible for a short period of time (forming basidiomes for a month or less). When it occurs, the number of individuals is usually big. In Brazil there are 32 records in Fungaria (splink.org.br).

Population Trend: Uncertain

Habitat and Ecology

Growing in small to large numbers in humic mat or in white sand soils in Dicymbe and Aldina dominated forests in the Guyana Shield and in restinga vegetation type in the forest floor, possibly associated with Nyctaginaceae and Polygonaceae.

Subtropical/Tropical Moist Lowland Forest


Threats include deforestation, burning, mining, and real estate speculation.

Conservation Actions

Many sites where this species is found in Brazil are protected areas, such as national parks. However the protected areas in Brazil are under constant attack by owners of adjacent land, real estate agencies, deforestation, mining and fire. Many of these areas, including indigenous land, are in danger of having their status changed by the government. Actions for conservation must include political action against changes in the status of protected areas and a better management of these areas.

Research needed

Better taxonomic and phylogenetic understanding of this taxon is needed, so we can understand its biogeography/distribution. Also, a better understanding of the plant symbionts, especially in the restinga, and their distribution would help to estimate this species’ distribution.

Use and Trade

This is an edible mushroom that is not yet highly consumed in any communities or by locals, but it has potential to be commercialized by locals and sold as an edible wild mushroom.
