Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 1000062 was collected by G. Robert, det: H. Romagnesi on 29th October 1953 in Malesherbes, Loiret, FRANCE (approx. 48.29°N, 2.41°E, altitude approximately 130 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Pinus) was present.

    The surrounding habitat was described as not recorded with a substrate of acidic soil.

    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.
