  • arrow_drop_downarrow_drop_upCollecting details

    Collection 13437 was collected by L. Samsø (JV-09-743 LSa2009-79355) on 31st October 2009 in Silkeborg Nordskov, EJ, DENMARK (56.1671°N, 9.5797°E, altitude approximately 65 m above sea level - Google maps). The ectomycorrhizal family Betulaceae (genus Betula) was present.

    The surrounding habitat was described as mixed woodland, 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 Baltic 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).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
