- arrow_drop_downarrow_drop_upCollecting details
Collection 11508 was collected by J. Volders (VJ96037) on 21st July 1996 in Lozerheide, Limburg, BELGIUM (51.1667°N, 5.5833°E, altitude approximately 40 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 boggy soil.
According to the GPS data the collection was in the European Atlantic mixed 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).
