Assessment Notes

All other Macowanites species were transferred to Russula. This species was not included in the study and was not transferred. The right name is probably Russula lilacinus (or similar), but it does not technically exist. I evaluated the species under Macowanites and noted this in the taxonomy section.

Justification

Macowanites lilacinus is a secotioid fungus only known from a single collection from North America from 1962. The lack of more recent records suggests this may be a rare species but more research and targeted search efforts are needed to estimate current population size. Additionally, its generic placement is uncertain. Therefore, the species is assessed as Data Deficient (DD).


Taxonomic notes

Only remaining species in genus Macowanites in Species Fungorum (2023). Other species in this genus were transferred to Russula based on molecular analysis (Elliott and Trappe, 2018), but M. lilacinus was not included in this study and therefore not transferred. For this reason, this species should be targeted for taxonomic revision.


Why suggested for a Global Red List Assessment?


Geographic range

The species is only known from one location in North America (Payette National Forest in Idaho)  (Smith, 1963).


Population and Trends

This species is only known from its description, from one collection in 1962 (Smith, 1963). Given the lack of any further records or information it is not possible to calculate current population size or trends.

Population Trend: Uncertain


Habitat and Ecology

The species was recorded as being solitary growing under spruce and fir (Smith, 1963).

Temperate Forest

Threats

Unknown.


Conservation Actions


Research needed

Taxonomic review is needed to confirm if it should be transferred into Russula like the other species formerly treated as Macowanites, Additionally,  targeted search efforts are needed to understand its current population size, distribution and habitat preference.
