Assessment Notes

This is one of the most common truffle-like fungi in Nothofagaceae forests in Chile and Argentina. It is associated with a wide array of Nothofagaceae host species in a variety of habitats, over a wide area. It is assessed as Least Concern.

Taxonomic notes

Cystangium species from South America are taxonomically confused with several species currently recognized (Trierveiler-Pereira et al. 2015). However, molecular data suggest that all of these Cystangium species may be synonyms (Smith et al., unpublished). Cystangium depauperatum Singer & A.H. Sm. is the oldest name and therefore has priority. Elasmomyces nothofagi E. Horak is a likely synonym. This species is currently being considered in the genus Russula as Russula depauperata (Singer & A.H. Sm.) Trappe & T.F. Elliott (in Elliott and Trappe 2018).

Geographic range

This species is found over a very broad area in Patagonia in many types of Nothofagacae forest.

Population and Trends

This species is very widespread and is among the most common truffle-like species of ectomycorrhizal fungi with Nothofagaceae host trees throughout southern South America.

Population Trend: stable

Habitat and Ecology

This is a common ectomycorrhizal fungus with Nothofagaceae host trees across a wide geographic area and in a number of different forest types.


Due to the widespread occurrence of this species in a variety of Nothofagaceae-dominated forests, there are currently no major threats that imperil this species.

Conservation Actions

No specific conservation actions are needed with regards to this species. However, additional molecular phylogenetic studies are needed to explore the species boundaries within Cystangium from Patagonia. If there are actually multiple cryptic species then this may affect our view of the conservation status.

Use and Trade

This species has no known human uses.
