- arrow_drop_downarrow_drop_upCollecting details
Collection 1000220 was collected by L. Quadraccia on 14th August 1984 in Monte Bondone (Trento), Torbiere della Viote, Trentino-Alto Adige/Südtirol, ITALY (46.012°N, 11.0239°E, altitude approximately 1550 m above sea level - Google maps). The ectomycorrhizal family Betulaceae (genus Betula) was present.
The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Alps conifer and 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).
