Collection 17038 was collected by W.G. McAdoo (BM-BMA159#1) on 29th October 1989 in Heady Road near Sumas, Whatcom County, Washington, UNITED STATES (approx. 48.9773°N, 122.1427°W, altitude approximately 170 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as mixed woodland with a substrate of mossy soil, 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 North Cascades conifer 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).
