- arrow_drop_downarrow_drop_upCollecting details
Collection 15669 was collected by U. Marulli, E. Grilli (EG-121201.01) on 1st December 2012 in Capo Pescara Nature Reserve, Parking Area, Popoli (PE), Abruzzo, ITALY (approx. 42.1658°N, 13.8216°E, altitude approximately 250 m above sea level - Google maps). The ectomycorrhizal family Salicaceae (genus Populus) was present.
The surrounding habitat was described as not recorded with a substrate of litter.
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).
