Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 10847 was collected by J. Vesterholt (91-550) on 9th October 1991 in Trelde Vesterskov N OF Fredericia. UTM NG5061, EJ, DENMARK (approx. 55.62°N, 9.76°E, altitude approximately 25 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Alnus) and Fagaceae (genus Fagus) were present.

    The surrounding habitat was described as not recorded with a substrate of nutrient-enriched soil.

    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.
