- arrow_drop_downarrow_drop_upCollecting details
Collection 1000039 was collected by G. Bruchet on 9th October 1964 in Les Echets near Lyon (Ain), FRANCE (approx. 45.86°N, 4.9°E, altitude approximately 280 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as not recorded with a substrate of clayey soil.
According to the GPS data the collection was in the Western European broadleaf forests WWF ecoregion The World Wildlife Fund (WWF) have divided the world into 867 terrestrial ecoregions. The ecoregion here is estimated by mapping from the GPS coordinates of the collection using data made available by Dinerstein et al (2017).
