Laccaria maritima (Theodor.) Singer ex Huhtinen, Fungi Canadenses 319: 1 (1987)

The Sand deceiver (Laccaria maritima) is rare and restricted to shifting dunes on nutrient-poor sandy soils where it forms ectomycorrhiza with Salix repens and Salix daphnoides (and possibly also other species such as Pinus). The species is vulnerable due to its rarity and the loss or impoverishment of its specific habitat.
The species is largely restricted to lowland parts of Europe but there are some records from North America ( Greenland, eastern Canada).
The Sand deceiver (Laccaria maritima) is specific for landscapes with shifting dunes on nutrient-poor sandy soils with no litter accumulation. The species forms ectomycorrhiza with Salix repens and Salix daphnoides and possibly also with other species such as Pinus. It mainly occurs in sandy shores along seas and large rivers and less often in inland dunes. The soil can be dry (dry dunes) to more or less wet (dune slacks). The stem of the fruitbodies is usually deeply buried in the sand and subsequently the cap height above the soil surface is very low.
Among the Natura 2000 habitat types (EU’s Habitat Directive) it occurs mainly in the habitat type 2020 ‘Shifting dunes along the shoreline with Ammophila arenaria (white dunes)’ and 2170 ‘Dunes with Salix repens ssp. argentea (Salicion arenariea)’. In addition there are records in 2130 ‘Fixed coastal dunes with herbaceous vegetation (grey dunes)’.
