- arrow_drop_downarrow_drop_upCollecting details
Collection 17796 was collected by D. Bartholow (SPFS-2011-63) on 26th September 2011 in Shaker Parklands, Doan Brook Gorge, Ohio, UNITED STATES (approx. 41.495°N, 81.5953°W, altitude approximately 275 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genera Quercus and Fagus) was present.
The surrounding habitat was described as not recorded with a substrate of grassy soil.
According to the GPS data the collection was in the Southern Great Lakes 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).
