- arrow_drop_downarrow_drop_upCollecting details
Collection 11344 was collected by I.O. Ibarguren (JV-05-602), det: H.J. Beker on 21st October 2005 in Rio Cerneja, Burgos, SPAIN (43.1178°N, 3.4609°W, altitude approximately 835 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Alnus), Fagaceae (genus Quercus) and Salicaceae (genus Salix) were present.
The surrounding habitat was described as deciduous woodland with a substrate of acidic, decomposed 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 Cantabrian 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).
