- arrow_drop_downarrow_drop_upCollecting details
Collection 9436 was collected by A. Andrews, det: H.J. Beker on 8th November 2003 in Mataelpino, Madrid, SPAIN (approx. 40.0479°N, 3.948°W, altitude approximately 1050 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as grassland with a substrate of burnt soil, 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. 4.4: Grassland – Temperate.
According to the GPS data the collection was in the Iberian sclerophyllous and semi-deciduous 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).
