Synonym: Craterellus melanoxeros (Desm.) Pérez-De-Greg
The species is limited to Europe. It is mainly present in the Atlantic, Central European and Alpine domains.
In 2015, the number of known sites were about 300, of which 50 % in France, where a decrease has been noticed for the last 30 years.
Cantharellus melanoxeros is ectomycorrhizal with trees in the Fagaceae, typically Fagus sylvatica and Quercus spp. (Q. robur and Q. petraea), possibly also Carpinus (France), in Sweden and UK also with Corylus avellana (Betulaceae). A few observations under Picea abies.
It occurs in deciduous (e.g. together with Castanea, Tilia) and mixed forests (with Pinus). In Central Europe it prefers warm sites. In more northern regions, it is found in boreo-nemoral oak forests. It avoids nitrogen-rich soils.
The species is found in the following Natura 2000 habitats (codes): 9020, 9050, 9070, 9110, 9120, 9130, 9150, 9160, 9170, 91A0, 9260.
Main threats are sylvicultural intensification (e.g. fertilization, clear cutting, exotic tree’ plantations) and by airborne nitrogen deposition.
