With apparently no record of this species for over 100 years it is not possible to accurately estimate its extinction risk. Therefore, Craterellus borealis is assessed as Data Deficient.
Why suggested for a Global Red List Assessment?
Craterellus borealis appears to only be known from the type collection made from ‘Gready Harbor’ (sic.) on ‘Gready Island’ (sic.) in Labrador, Canada (Burt 1914). It is assumed that this locality is Grady Harbor on Grady Island.
Population and Trends
It is not currently possible to estimate the population size or trend.
Population Trend: Uncertain
Habitat and Ecology
The type collection was made amongst moss in August 1908 (Burt 1914), but no general habitat requirements were noted by Burt (1914).
Without further information regarding its full distribution, it is not possible to infer what threats this species may be facing.
Work should be conducted to rediscover the species, and get a clearer idea of its distribution, habitat and population. It is possible that further taxonomic work may also be required as part of a review of the genus.
