Collection 1000325 was collected by C.A. Barrows (3056), det: A.H. Smith in September 1965 in Santa Fe, Hyde Park Rd near Santa Fe, New Mexico, UNITED STATES (approx. 35.7288°N, 105.867°W, altitude approximately 2390 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as mixed, 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 Colorado Rockies 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).
