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.
It occurs in white sand forests along the Guyana Shield, including the Brazilian Amazon, Venezuela, Colombia, Guyana and French Guiana, and also on restinga vegetation in the Atlantic rainforest in the north-east 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 large. In Brazil there are 32 records in Fungaria (splink.org.br).
Population Trend: unknown
Habitat and Ecology
It grows in small to large numbers in humic mats or in white sand soils in Dicymbe
dominated forests in the Guyana Shield and in restinga vegetation, possibly associated with Nyctaginaceae and Polygonaceae.
Threats include deforestation, burning, mining, and real estate speculation.
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. Actions for conservation must include political action against changes in the status of protected areas and a better management of these areas.
Additionally, 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 commercialised by locals and sold as an edible wild mushroom.
