Description

Collecting details

Collection 13284 was collected by M. Todoroska on 27th September 2009 in Paradis Dune near Nida, Curonian Spit, LITHUANIA (55.2952°N, 20.9861°E, altitude approximately 25 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Salicaceae (genus Populus) were present.
The surrounding habitat was described as mixed dune woodland with a substrate of mossy 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.
