Assessment Notes
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.
