Collection 1000286 was collected by F.S. Earle (FSE51), det: W.A. Murrill on 12th November 1901 in Bronx Co., New York Botanical Garden, New York, UNITED STATES (approx. 40.8621°N, 73.8769°W, altitude approximately 750 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Fagus) 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 Northeast US Coastal 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).
