Cantharellus isabellinus has undergone taxonomic revision in recent years, with variety parvisporus having been split as a separate species. As such all records of this species from miombo woodland are considered to be dubious. Based on the newly circumscribed species, it is still suspected to have a very wide range in Central Africa. Confirmed records come from Democratic Republic of Congo and Cameroon, but it occurs in Gilbertiodendron dewevrei forest, and so is likely to be even more widespread. Overall, therefore, C. isabellinus is assessed as Least Concern.
Why suggested for a Global Red List Assessment?
Cantharellus isabellinus was originally described from Binga in northern Democratic Republic of Congo (Heinemann 1958). There have been further collections in this country, and others from Cameroon (GBIF.org, Buyck et al. 2018, Kamalebo et al. 2019). These records from Cameroon have been noted from Gilbertiodendron dewevrei forest, and so its distribution is suspected to be large in Central Africa.
Records from miombo woodland appear to be in error (Buyck et al. 2013), especially since Buyck et al. (2018) split variety parvisporus (from Tanzania) as a separate species.
Population and Trends
There is no quantitative information regarding population size and trend.
Population Trend: Uncertain
Habitat and Ecology
The type description was from dry forest (Heinemann 1958), while recent studies suggest Gilbertiodendron dewevrei as a potential host (Buyck et al. 2018, Kamalebo et al. 2019).
There may be localised threats to this species from logging, land conversion for agriculture and mining; all exacerbated by road construction. However, the overall impact of these on the species’ status as a whole is uncertain.
