- arrow_drop_downarrow_drop_upCollecting details
Collection 11704 was collected by H.J. Beker on 7th October 2006 in Foret Andaines, Normandy, FRANCE (48.5808°N, 0.4583°W, altitude approximately 170 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genera Fagus and Quercus) was present.
The surrounding habitat was described as mixed woodland with a substrate of boggy soil and litter, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 1.4: Forest – Temperate.
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).
