Assessment Notes

Taxonomic notes

Cantharellus borealis was described in 1971 by Petersen & Ryvarden and listed in Index of Fungi in1981.

A more recent phylogenetic study suggested that C. borealis should be placed in Craterellus and is close or conspecific with Craterellus lutescens (Olariaga et al, 2017). The authors advised undertaking a comparison with C. lutescens to ascertain the placement of C. borealis.


Why suggested for a Global Red List Assessment?

Chanterelle species to be assessed as part of the chanterelle comprehensive project.


Geographic range

C. borealis was described from Norway, but there are very few georeferenced available subsequent to its description. GBIF also lists 7 observational records from Slovenia over the period 1974-2004, where it has been repeatedly identified by different recorders. A less certain record of C.borealis from the eastern Amur region in Russia is listed from a biology student’s project on fungi of that region (Kochunova, 2015).

Range extent is uncertain as occurrence data is very limited. However, under a tentative assumption that the records from Slovenia and Russia are accurate, the range could extend across much of Eurasia where the habitat is suitable. The type description highlights that the distribution of C. borealis could be more widespread across the northern part of Fennoscandia and further eastwards into Russia where there is a favourable bedrock.

The KML polygon file attached is an inferred range of C. borealis based on existing occurrence records and distribution of Carex capillaris in Eurasia, one of the two Carex species named in the type description as forming the wet meadow grass habitat.


Population and Trends

Population estimates depend on the assumptions about the inferred range. Given the broad range of Carex species thought to make up its habitat and the existing widely distributed records it can tentatively be assumed to occur across Eurasia where appropriate habitat exists.

Wet meadows may have declined through changing land use in parts of this distribution, so there may be a decreasing population trend, but the few spatio-temporal records mean this may be too strong an inference.
