Collection 19754 was collected by J. Horman on 27th October 2007 in Southaven, Southaven State Park, Suffolk County, Long Island, New York, UNITED STATES (approx. 40.8°N, 72.98°W, altitude approximately 20 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Atlantic coastal pine barrens 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).
