Collection 1000146 was collected by F. Esteve-Raventós, det: F. Esteve-Raventós, Heykoop on 10th November 1985 in Puerto de Canencia, Madrid, SPAIN (approx. 40.87°N, 3.77°W, altitude approximately 1500 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) 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 Iberian conifer 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).
