Assessment Notes

Justification

Gomphogaster leucosarx is a secotioid fungus known from a single collection in 1958 in North America. The lack of any more records suggest this may be a rare species, but targeted search efforts are needed to confirm this. The placement of G. leucosarx in the Gomphogaster genus has also been questioned and should be further reviewed. For now it is assessed as Data Deficient (DD).


Taxonomic notes

Originally described as Brauniellula leucosarx, this species was later transferred to the monotypic genus Gomphogaster based on its morphogical characteristics. The Gomphidiaceae family has since been reviewed using phylogenetic analysis (Miller Jr, 2003), but it was not possible to study G. leucosarx at the time because its holotype collection consists of a single fruiting body. Nevertheless, authors noted that G. leucosarx will likely be transferred do Gomphidius in the future.


Why suggested for a Global Red List Assessment?


Geographic range

Known from a single location in Payette National Forest in Idaho (Smith and Singer, 1958).


Population and Trends

Species is known from a single specimen found in 1958. Given the lack of more recent records or search attempts it is not possible to estimate population size.

Population Trend: Uncertain


Habitat and Ecology

Likely mycorrhizal with Pinaceae (Miller Jr, 2003). Found under Pinus contorta, solitary. (Smith and Singer, 1958)

Temperate Forest

Threats

Unknown.


Conservation Actions


Research needed

Review of its taxonomic placement is needed, as well as targeted search efforts to estimate population size and determine habitat preferences and distribution.
