Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 12529 was collected by D.K. Aanen on 5th October 1995 in Roden, Drenthe, NETHERLANDS (approx. 53.13°N, 6.43°E, altitude approximately 0 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Carpinus) and Fagaceae (genus Fagus) were present.

    The surrounding habitat was described as not recorded.

    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).

(biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfb (Temperate, no dry season, warm summer).

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.
