  • arrow_drop_downarrow_drop_upCollecting details

    Collection 9153 was collected by M. Ghyselinck, det: H.J. Beker on 29th November 2003 in Chiens, Namur, BELGIUM (approx. 50.38°N, 4.59°E, altitude approximately 170 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Pinus) was present.

    The surrounding habitat was described as mixed woodland with a substrate of calcareous, 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 European Atlantic 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).
