- arrow_drop_downarrow_drop_upCollecting details
Collection 12512 was collected by D.K. Aanen on 22nd September 1996 in Lac des Rouges Truites, Jura, FRANCE (46.3625°N, 5.5953°E, altitude approximately 940 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Salix) was present.
The surrounding habitat was described as subalpine shrubland, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 3.3: Shrubland – Boreal.
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).

(biome: Temperate Broadleaf & Mixed Forests) and Koppen climate code Cfb (Temperate, no dry season, warm summer).
