- arrow_drop_downarrow_drop_upCollecting details
Collection 13151 was collected by I. Kałucka on 4th October 1995 in Jelonka Reserve (undisturbed), POLAND (approx. 52.595°N, 23.359°E, altitude approximately 180 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Betula), Pinaceae (genus Pinus) and Salicaceae (genera Populus and Salix) were present.
The surrounding habitat was described as mixed woodland with a substrate of acidic 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 Central European mixed 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).
