Why suggested for a Global Red List Assessment?

This is an endemic species from from the Polylepis australis forests (Argentina), an environment that is heavily invaded and whose surface has been reduced to a minimum of its original extension.

Geographic range

endemic to central and northern Argentina. Restricted to the Polylepis australis forests on the Sierras Pampeanas range.

Population and Trends

Given the low number of findings in an area that was intesively researched for many years, we estimate that the population in terms of fruiting bodies must be really low ans we assing a tentative number of 10000. Since fruiting bodies are exposed and not hidden, we assume that they shoud be easy to find. This indicates that the estimation is more realistic that in the case of inconspicuous species.

Population Trend: Decreasing

Habitat and Ecology

Restricted to twiglets of living Polylepis australis trees.

Subtropical/Tropical Dry Forest


fragmentation and and severe reduction of the habitat as well as invasion of the forest by non native trees and shrubs as Ligustrum lucidum of Pyracantha coccinea.  Gallo et al. 2015 intensively sampled these forests and showed that the occurrence of the species is inversely correlated with the degradation status of the forest.

Housing & urban areasAgro-industry grazing, ranching or farming

Conservation Actions

Research strategies focusing on the conservation of the environment are being developed and political actions pointing to stop the reduction of the natural range. Some natural reserves constitute a reservoir of the species, However, fire and cattle still affect the recovering of the host population there and the invasions are still progressing.

Resource & habitat protectionInvasive/problematic species control

Research needed

host spescificity studies are needed as well as information on occurrence in isolated populations o the host. The presence in other species of Polylepys would mean a lower risk status for the species, but it has not been detected yet.
