- arrow_drop_downarrow_drop_upCollecting details
Collection 19759 was collected by P. Marstad (17-98) on 11th July 1998 in Vestfold, Tønsberg, Kjellelia, NORWAY (approx. 59.2929°N, 10.3957°E, altitude approximately 0 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as not recorded with a substrate of nutrient-enriched soil.
According to the GPS data the collection was in the Scandinavian and Russian taiga 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).
