Collection 10854 was collected by A. Eriksen, J. Vesterholt (JV-03-547), det: J. Vesterholt on 26th September 2003 in Kirkemilen,Skagen Klitplantage UTM NJ 91,97 TBU 01, NEJ, DENMARK (approx. 57.71°N, 10.55°E, altitude approximately 5 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Salicaceae (genus Salix) were present.
The surrounding habitat was described as coniferous woodland plantation with a substrate of sandy soil, 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. 1.4: Forest – Temperate.
According to the GPS data the collection was in the Koppen climate code Cfb (Temperate, no dry season, warm summer).
