Assessment Notes

Taxonomic notes

Difficult to identify as microscopy is needed to reliably distinguish it from other species of the genus. A considerable number of records are potentially based on misidentifications. Originally described from the environs of Paris (Fontainbleau) from where an epitype based on a newly collected sample should be selected and sequenced.


Why suggested for a Global Red List Assessment?

A widely distributed species forming ectomycorrhiza with various trees. Although the records from different parts of the world need checking for conspecificity, the population in Europe (its core area from where it was originally described) seems to be stable.  LC is proposed.


Geographic range

Cosmopolitan distribution in temperate regions. N. America, Europe, Australia. However the total distribution range is ambiguous due to misidentifications. Reported as common on the Iberian peninsula. Scattered records in northern Europe, reaching southern Sweden and Norway (nemoral vegetation). Recorded as eDNA-sequences from Estonia. Erroneous record from Greenland based on e-DNA.


Population and Trends

Although redlisted on the C-criterium in some countries in northern Europe, the global population does not show a decline according to current knowledge. However distribution records are ambiguous due to potential misidentifications.

Population Trend: Stable


Habitat and Ecology

Ectomycorrhizal with Quercus, Fagus and other deciduous trees, probably also Pinus spp. In Europe it occurs mainly in the nemoral vegetation but is regularly found also in the Mediterranean region. It occurs in semi-open woodland and in meadows and pastures with scattered mycorrhizal trees, but it is also found also in gardens, along road verges etc.


Threats


Conservation Actions


Research needed

Given the wide distribution of this species, conspecificity of samples from around the world should be investigated using molecular methods. An epitype for S. cepa should thus be designated to fix the species concept.


Use and Trade

None
