Collection 14706 was collected by R. Lebeuf (HEB0922-1) on 22nd September 2015 in Cosby, Great Smoky Mountains, Tennessee, UNITED STATES (approx. 35.8155°N, 83.2478°W, altitude approximately 400 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genera Fagus and Quercus) was present.
The surrounding habitat was described as not recorded with a substrate of soil.
According to the GPS data the collection was in the Appalachian-Blue Ridge 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).
