- arrow_drop_downarrow_drop_upCollecting details
Collection 17386 was collected by A. Zuccherelli, det: E. Grilli (971011.01) on 11th October 1997 in Fossatone, Pineta di San Vitale, Ravenna, (RA), Emilia-Romagna, ITALY (44.5059°N, 12.2316°E, altitude approximately 0 m above sea level - Google maps). The ectomycorrhizal families Salicaceae (genus Populus) and Fagaceae (genus Quercus) were present.
The surrounding habitat was described as deciduous woodland with a substrate of soil and litter, 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 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).
