Collection 1000082 (herbarium acc. no. NYS-F-000108) is Hebeloma sporadicum.Description
- arrow_drop_downarrow_drop_upCollecting details
Collection 1000082 was collected by C.H. Peck in October 1909 in Bethlehem, Albany, New York, UNITED STATES (approx. 40.62°N, 75.36°W, altitude approximately 80 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 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).
