Description

Collecting details

Collection 17975 was collected by H.J. Beker, L. Davies on 31st August 2018 in Railway Station, Whitehorse, Yukon, CANADA (60.7215°N, 135.0506°W, altitude approximately 665 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genera Populus and Salix) was present.
The surrounding habitat was described as boreal shrubland riverside with a substrate of soil and litter, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 3.3: Shrubland – Boreal.
According to the GPS data the collection was in the Watson Highlands 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.
