Collection 12913 was collected by G. Bruchet on 24th October 1966 in Notre-Dame-des-Lumieres, Vaucluse, FRANCE (approx. 43.82°N, 5.28°E, altitude approximately 250 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genera Populus and Salix) was present.
The surrounding habitat was described as not recorded with a substrate of decomposed litter.
According to the GPS data the collection was in the Northeast Spain and Southern France Mediterranean 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).
