- arrow_drop_downarrow_drop_upCollecting details
Collection 1000101 was collected by R. Maire on 20th October 1933 in Catalaunia, Palautordera, Barcelona, SPAIN (approx. 41.7°N, 2.4°E, altitude approximately 210 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Fagaceae (genus Quercus) were present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Northeast Spain and Southern France Mediterranean 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).
