Collection 1000539 was collected by A.H. Smith (90215) on 3rd September 1979 in Elk Camp, Burnt Mountain, Pitkin County., Colorado, UNITED STATES (approx. 39.1875°N, 106.9352°W, altitude approximately 3000 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genera Abies and Picea) was present.
The surrounding habitat was described as coniferous, subalpine woodland, 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Ordos Plateau steppe 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).
