- arrow_drop_downarrow_drop_upCollecting details
Collection 16439 was collected by E. Bizio, det: E. Bizio, E. Grilli (EG-121019.01) on 19th October 2012 in San Nicolò, Lido di Venezia, Veneto, ITALY (45.4287°N, 12.3931°E, altitude approximately 10 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Populus) was present.
The surrounding habitat was described as deciduous dune woodland with a substrate of mossy, 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. 13.3: Coastal Sand Dunes.
According to the GPS data the collection was in the Po Basin 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).
