- arrow_drop_downarrow_drop_upCollecting details
Collection 11858 was collected by J. Vesterholt (06-1153) on 11th November 2006 in 2km south of Massa Maritimo along road to Capanne, Grosseto, Tuscany, ITALY (approx. 44.02°N, 10.15°E, altitude approximately 45 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as mixed woodland, 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 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).
