Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 13086 was collected by E. Campo on 10th December 2006 in Pordenone, Sacile, Topaligo, Friuli-Venezia Giulia, ITALY (45.5637°N, 12.2936°E, altitude approximately 25 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Populus) was present.

    The surrounding habitat was described as not recorded.

    According to the GPS data the collection was in the Po Basin 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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfa (Temperate, no dry season, hot 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.
