Assessment Notes

Justification

Cantharellus nothofagorum is currently known only from its type collection in Argentina. Further information regarding any current populations of this species appears to be lacking. The type specimen was found growing along a steep road bank in bare soil, within mature moist Nothofagus dombeyi forest, at an altitude of 900-950m. Nothing is known of any existing present day subpopulations. If the species were to be shown to restricted to only its known sites then it potentially could be Critically Endangered, but if it is more widespread across Nothofagus dombeyi forest then it could be classed as Least Concern. With this high a level of uncertainty, then C. nothofagorum is assessed as Data Deficient.

Geographic range

The only information available regarding the distribution of this species comes from its type specimen from 1988. This specimen was located in Argentina, between Confluencia and Route 234, approximately 10km east of Route 234 at Paso El Portezuelo on Route 65 (Petersen and Mueller 1992). This specimen is preserved by the Field Museum of Natural History (Botany) Fungi Collection with information available at GBIF (2020). It is assumed that the identification as 'Route 234' is an error because the site of Paso El Portezuelo on Route 65 is instead to the east of Route 40.

Population Trend: unknown

Habitat and Ecology

The genus Cantharellus consists of species that form ectomycorrhizal associations with trees. The type specimen of this species was found growing along a steep road bank in bare soil, within mature moist Nothofagus dombeyi forest, at an altitude of 900-950m (Petersen and Mueller 1992).

Threats

Wild subpopulations of this species could be threatened by human disturbance, as well as logging, and non-timber agriculture. Nothophagus dombeyi, which this fungus appears to associate with, is not thought to be threatened, listed as Least Concern (Barstow et al. 2017).

Conservation Actions

This species appears to exist under preservation, with the only known site being in the Parque Nacional Nahuel Huapi. However, its known habitat is thought to be under threat. Protection of this habitat is recommended. Surveys are required to describe the ecology and to identify how widespread this species could be.
