Collecting details

Collection 13232 was collected by I. Kałucka, H.J. Beker on 21st September 2009 in Czerwona Szopa, Slowinski National Park (Slowinski Park Narodowy), POLAND (54.7191°N, 17.2188°E, altitude approximately 0 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Pinus) was present.
The surrounding habitat was described as mixed dune woodland with a substrate of bare, nutrient-enriched 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. 13.3: Coastal Sand Dunes.
According to the GPS data the collection was in the Koppen climate code Dfb (Cold, no dry season, warm summer).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
