Assessment Notes


This species has only been recorded from four sites, but these are widely spaced and there is a lot of suitable habitat in between. It is likely that its population is quite large, and that any declines are not significant enough to place it into a threatened category. It is therefore assessed as Least Concern.

Taxonomic notes

This species was recently described by Kumar et al. (2017).

Why suggested for a Global Red List Assessment?

Paurocotylis patagonica is a rare truffle species found in Nothofagaceae-dominated or mixed forests in Patagonia. This truffle species is apparently rare and is currently only known from four locations.

Geographic range

Paurocotylis patagonica is a rare truffle species found in mixed forests of Patagonia. This truffle species has only been collected four times in Chile and Argentina.

Population and Trends

This species is only known from four sites; three in northern Patagonia and one significantly further south, near the southern tip of Chile. Considering the large area of potential habitat, and its low detectability, it is likely that its population exceeds 1000 mature individuals. Although it may be declining in the northern portion of its range, the southern areas are more secure, and so the overall population trend is uncertain.

Population Trend: Uncertain

Habitat and Ecology

The ecology of the genus Paurocotylis is not well understood. This genus was originally considered to be mycorrhizal by some authors but available data suggest that members of this genus (and the related genera Geopyxis, Hydnocystis and Densocarpa) do not form mycorrhizas. Available evidence suggests that species in this group may act as endophytes during part of their lifecycle but may also act as saprobes.

Subantarctic ForestTemperate Forest


This species has only been found in well-preserved Nothofagaceae or mixed Nothofagaceae forests in southern Chile and Argentina. Any threats (e.g. logging and grazing) which reduce forest quality and extent will potentially impact this species, but these are not considered to be major threats at present.

Conservation Actions

At least some populations of this species occur in National Parks in both Chile and Argentina (e.g. Parque Nacional Puyehue, Andino Norpatagónica Biosphere Reserve) and it is likely that more populations occur between the northern and southern portions of the range. Accordingly, no specific conservation actions are required at this time.

Research needed

The ecology and distribution of this species are poorly known.
