This species is known from one site in Guyana, where a tiny fraction of its possible suitable habitat has been surveyed. Potential host plants occur in a large region encompassing parts of Venezuela, northern Brazil and southeast Colombia. This entire region is very under-sampled, being very remote and completely unsurveyed. In total approximately 0.002% of its potential suitable habitat has been surveyed for fungi. It is not possible to estimate population size or trends, EOO, or AOO. Increasing threats from timber and mineral extraction, and land use changes are anticipated, with the potential for these to be rapid if further road construction occurs. It is therefore assessed as Data Deficient, and further survey work in this region is urgently needed.

Its currently known distribution is restricted to Dicymbe-dominated forests in the Guiana Shield region where it is known collections at a single site; Potaro-Siparuni, Pakaraima Mountains, Upper Potaro River Basin, 20 km east of Mount Ayanganna, environs of base camp on Potaro River 1 km upstream from confluence of Whitewater Creek at 5u18904.8N, 59u54940.4W, 710–750 m.

This entire region is very under-sampled, and there are areas in neighbouring Venezuela, northern Brazil and southeast Colombia with similar habitats but which are very remote and completely unsurveyed.

Solitary, fruiting in mosses on a standing dead snag and from humus on the side of a living trunk in forests dominated by Dicymbe corymbosa during May–July rainy season. Known only from the type locality in the Upper Potaro River Basin of Guyana.

Current threats include climate change and small-scale mineral extraction that can cause habitat disturbance and water pollution although these threats are currently not thought to be severe as much of the interior of the region is very remote. Future threats from timber and mineral extraction, and land use changes are anticipated, with the potential for these to be rapid if further road construction occurs. Further impacts of climate change, particularly droughts, are also anticipated.

No conservation actions are currently in place for this species. Protection of habitat is needed.

Additional survey work to document the species’ distribution and abundance, taxonomy, and life history are needed.

There are no known uses of this species.
