- arrow_drop_downarrow_drop_upCollecting details
Collection 1000137 was collected by M. Enderle, det: J. Vesterholt on 9th September 1994 in near Riedheim, Gunzberg, MTB7527/1 (in Naturschutzgebiet), Bavaria, GERMANY (approx. 48.462°N, 10.189°E, altitude approximately 455 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Betula) and Salicaceae (genus Salix) were present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Western European broadleaf 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).
