- arrow_drop_downarrow_drop_upCollecting details
Collection 11514 was collected by X. Llimona, J. Vila, T. Jimenez on 14th December 2002 in Can Ferrer (Barcelona), Barcelona, SPAIN (approx. 41.67°N, 2.21°E, altitude approximately 285 m above sea level - Google maps). The ectomycorrhizal family Cistaceae (genus Cistus) was present.
The surrounding habitat was described as maquis with a substrate of acidic 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. 3.8: Shrubland – Mediterranean-type shrubby vegetation.
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).
