There is a degree of taxonomic confusion with regards to the use of this binomial, with scattered reports from three different continents. Getting clear identifications of specimens, and getting a conclusive decision on the taxonomic position of Cantharellus rhodophyllus and C. subincarnatus will be useful. However, irrespective of this, based on the known records for C. rhodophyllus, and its potential ecological requirements, it is likely to be widespread through Central Africa. Therefore, even with the current taxonomic confusion, this species is not thought to approach the thresholds for listing as threatened under any criterion and is assessed as Least Concern.
Why suggested for a Global Red List Assessment?
The type specimen of this species was collected at Binga, northern Democratic Republic of Congo (Heinemann 1958). The epitype for the species was collected in Dzanga-Sangha Forest Reserve, southern Central African Republic, under Gilbertiodendron dewevrei (Buyck and Hofstetter 2018). As such it could have a wide distribution across equatorial forest in Central Africa. There is some taxonomic uncertainty around this concept though, depending on whether Cantharellus subincarnatus is treated as a synonym or not of C. rhodophyllus (Buyck and Hofstetter 2018 place it as a synonym, but Index Fungorum does not). Irrespective of this, though, given the known records of this species within Africa, it is possible to suspect a wide range, and there are non-georeferenced records from Gabon and Cameroon (GBIF.org).
The species has also been included in a list of Colombian macrofungi (Vasco-Palacios and Franco-Molano (2013), and the Himalayas (Kumari et al. 2011); although these records would represent significant extensions to the range, and probably require further research to verify them. GBIF records from Madagascar potentially do not represent this species, especially given the taxonomic uncertainty between this species and C. subincarnatus, with C. sunincarnatus ssp. rubrosalmoneus (only known from Madagascar) having been proposed as a separate species (Buyck and Hofstetter 2018).
Population and Trends
Population size and trend are essentially unknown.
Population Trend: Uncertain
Habitat and Ecology
This species has been collected in dense Gilbertiodendron dewevrei forest, and Macrolobium forest (Heinemann 1958, Ndong et al. 2011, Buyck et al. 2018)
With the taxonomic uncertainty, it is difficult to identify specific threats to this species. However, if it were to be shown to have a wide distribution then it would not be expected to be facing any major threats to its persistence.
Despite the recent work by Buyck and Hofstetter (2018), there does appear to be taxonomic confusion with regards to this species. A further synthesis to confirm the taxonomic position of this species, and all specimens currently ascribed to it and Cantharellus subincarnatus should be re-evaluated to confirm the overall position. This could also lead to identification of further species in Colombia and the Himalayas.
