Assessment Notes

Justification

Cantharellus betularum is a recently described species of chanterelle from Newfoundland, Canada.

It is currently known from three locations, despite years of surveying the fungi of Newfoundland and Labrador, Canada. Suitable habitat is widespread, and not tied to any large scale decline.

Until this species is better known, and attempts have been made to locate C. betularum in similar habitat in other parts of Northeast North America, I recommend listing this species as Data Deficient (DD).


Taxonomic notes

Cantharellus betularum was first reported as North American records of C. amethysteus (Thorn et al. 2017), before being described as a distinct species (Thorn et al. 2020).


Why suggested for a Global Red List Assessment?

Cantharellus betularum is a recently described species of chanterelle from Newfoundland, Canada.

It is currently known from three locations, despite years of surveying the fungi of Newfoundland and Labrador, Canada. Suitable habitat is widespread, and not tied to any large scale decline.

Until this species is better known, and attempts have been made to locate C. betularum in similar habitat in other parts of Northeast North America, I recommend listing this species as Data Deficient (DD).


Geographic range

Currently known from three locations in the Bay of Islands region of western Newfoundland, Canada (Thorn et al. 2020).


Population and Trends

Cantharellus betularum is a recently described species, currently known from three locations in Newfoundland, Canada. Data to assess population size and trends is lacking. Suitable habitat is widespread; but to date, despite years of work on the fungi of Newfoundland and Labrador, Canada, it has not been found outside a small area on the west coast of Newfoundland.

Population Trend: Uncertain


Habitat and Ecology

Cantharellus betularum is an ectomycorrhizal species associated with birch (Betula papyrifera, B. cordifolia and B. alleghaniensis) (Thorn et al. 2020). Fruiting are solitary or in colonies among leaf litter of Betula (Thorn et al. 2017, Thorn et al. 2020).

Boreal Forest

Threats

Use and Trade

Cantharellus betularum is edible, and most chanterelles are indiscriminately collected by foragers and small scale commercial pickers.
