Collection 17268 was collected by S. Gamiet, V. Sterenberg (SG-269) on 15th September 2017 in Yellowknife, Ingraham Trail, Prelude West, Northwest Territories, CANADA (approx. 62.5773°N, 114.0541°W, altitude approximately 185 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genus Salix) and Betulaceae (genus Betula) were present.
The surrounding habitat was described as mixed woodland with a substrate of sandy 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the Northern 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).
