This species is only known to occur within the Tbilisi National Park, Georgia, and has been found growing under Fagus orientalis in probably calcareous soil. If it were to be restricted to this one site then it could be threathened and qualify for criterion D. However, it may probably be more widespread witthin the distribution of calcareous F. orientalis forests. Given the high levels of uncertainty C. roseofagetorum is assessed as Data Deficient.
Why suggested for a Global Red List Assessment?
The holotype of this species was collected in Georgia, Ghulelebi, Tbilisi National Park, under Fagus orientalis on probably calcareous eutric cambisol soil, in 2012 (Olariaga et al 2017, and see documentation in Gbif ). A further specimen was found in the same locality with scattered Malus and Taxus baccata, on probably calcareous ground, at the same time as the holotype was collected. No further records of this species appear to be available.
Population and Trends
There is no quantitative information regarding population size and trend. This only known site for the species is under protection of the Tbilisi National Park.
Population Trend: Stable
Habitat and Ecology
The genera Cantharellus consists of species forming ectomycorrhizal associations with trees. This species has been found in the Tbilisi National Park under Fagus orientalis and with scattered Malus and Taxus baccata, on probably calcareous ground and calcareous eutric cambisol soil.
This species appears to exist entirely under protection of the Tbilisi National Park, and so it is unlikely to be significantly threatened.
Surveys are required to describe the ecology and to identify how widespread this species could be.
