An ectomycorrhizal species with a small population restricted to a well defined habitat which is threatened by exploitation. The habitat loss/decline is historical and ongoing.
Known AOO: 800 km2
Suggested assessment :VU (B2b) or NT-VU (A)
Scandinavia, Iceland, Poland, Slovakia, northern part of the USA, Canada. Reaches north to appr. 67 N in Sweden. Markedly northern boreal distribution with rare southerly outposts in sandy areas of Central Europe.
Appr 550 records on GBIF database.
AOO 800 km2
EOO 9300000 km2Estimated number of localities: 1000
Estimated number of mature individuals: 20000Expected habitat decline/loss due to exploitation of localities (summer houses, camping sites, roads, buildings); historical and ongoing decline.
Population Trend: Uncertain
Ectomycorrhizal with Pinus spp (and potentially with small Salix species, eg. S. repens) in dry and sandy habitats: sandy beaches, maritime sand dunes, inland sanddunes, sandy river banks; also in anthropogeneous habitats: old church yards and camping sites on sandy soil. Mostly exposed habitats with scattered pine trees. Fruitbodies occur in patches with naked sand.
Redlisted as NT (A) in Sweden
Localities with S. septentrionale should be regularly monitored and protected from exploitation by construction works. Moderate soil disturbance, creating and maintaining patches with naked sand, favours its fructification.
