- arrow_drop_downarrow_drop_upCollecting details
Collection 13663 was collected by H.J. Beker on 6th October 2010 in S. Maurizio, Piedmont, ITALY (44.3631°N, 7.4633°E, altitude approximately 890 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genera Abies and Pinus) was present.
The surrounding habitat was described as coniferous churchyard parkland with a substrate of grassy 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. 14.5: Urban Areas.
According to the GPS data the collection was in the Italian sclerophyllous and semi-deciduous 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).
