- arrow_drop_downarrow_drop_upCollecting details
Collection 16088 was collected by D. Wasilewski on 30th October 2016 in Nescopeck State Park, Pennsylvania, UNITED STATES (approx. 41.0911°N, 75.8798°W, altitude approximately 350 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genus Populus) and Fagaceae (genus Quercus) were 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 Allegheny Highlands 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).
