Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/266014628/266021335

Justification

Ixocomus australiuralensis was described from eastern European Russia in 1955, but has not been recorded since and there is no further documentation on it. It is likely that this species has been forgotten to science, and a taxonomic review is needed to confirm its placement in the genus Ixocomus. The species is assessed as Data Deficient (DD).

Taxonomic notes

Ixocomus australiuralensis is the only remaining species in the genus Ixocomus. Other species formally treated in the genus have been transferred, mostly to the genus Suillus (Species Fungorum 2023).

Geographic range

The species was described from eastern European Russia (Species Fungorum 2023).

Population and Trends

There are no records or documentation on this species other than its description in 1955, so it is not possible to estimate the current population size or trends.

Population Trend: Unknown


Habitat and Ecology

The description states that the specimen was found in open woods of Pinus sylvestris (see Species Fungorum 2023).

Threats

This species' threats are unknown.

Conservation Actions

Given that other species in the genus have been transferred to other genera, a review of Ixocumys australiuralensis’ taxonomic placement is recommended. Research into its ecology, distribution and population size is also needed.
