Assessment Notes
Justification
Craterellus flavobrunneus is a mushroom of North America confirmed from only Nova Scotia, Canada. With the paucity of information available for this species it is currently not possible to accurately assess the extinction risk that it faces and so
C. flavobrunneus is listed here as Data Deficient.
Geographic range
This species is known from the original collection (described as a
Cantharellus but latterly moved to
Craterellus) at Black Hole near to Baxter's Harbor in Nova Scotia, Canada (see Buyck
et al. 2010). There is another possible record from the west side of Priest Lake in Idaho, USA, but the specimen collected was identified as '
Cantharellus flavobrunneus ?', suggesting a degree of uncertainty over its identity (see GBIF 2022).
Population and Trends
The overall population size and trend are unknown.
Population Trend: Unknown
Habitat and Ecology
The type collection was made from underneath spruce and birch (see Buyck
et al. 2010).
Threats
Further information is required regarding the overall distribution of the species before an accurate assessment of its threats can be made.
Conservation Actions
Work is needed to better estimate the full extent of the distribution of
Craterellus flavobrunneus, including further investigations into the potential collection from Idaho.
