  • arrow_drop_downarrow_drop_upCollecting details

    Collection 18626 was collected by R. Lebeuf on 30th August 2018 in Radisson, Hydro Radisson, Quebec, CANADA (approx. 53.792°N, 77.616°W, altitude approximately 180 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genera Pinus and Picea) and Salicaceae (genus Salix) were present.

    The surrounding habitat was described as not recorded.

    According to the GPS data the collection was in the Eastern Canadian Shield taiga 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.
