- arrow_drop_downarrow_drop_upCollecting details
Collection 14627 was collected by M. Contu, det: E. Grilli (921205.01) on 5th December 1992 in Serramanna, Sardinia, ITALY (approx. 39.4225°N, 8.9217°E, altitude approximately 40 m above sea level - Google maps). The ectomycorrhizal family Myrtaceae (genus Eucalyptus) was present.
The surrounding habitat was described as not recorded with a substrate of decomposed litter.
According to the GPS data the collection was in the Tyrrhenian-Adriatic sclerophyllous 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).
