- arrow_drop_downarrow_drop_upCollecting details
Collection 10650 was collected by J. Vesterholt (03-585) on 3rd October 2003 in Toscana, prov. Arezzo, comm Sestino, Casale., Tuscany, ITALY (approx. 43.72°N, 12.33°E, altitude approximately 600 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as not recorded with a substrate of calcareous soil.
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).
