Description

Collecting details

Collection 10883 was collected by J. Vesterholt (03-856) on 15th November 2003 in Castell'Umberto,prov. Messina, Area ecologica, Sicily, ITALY (approx. 38.08°N, 14.8°E, altitude approximately 580 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.
The surrounding habitat was described as not recorded.
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).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
