Collection 10657 was collected by J. Vesterholt (03-858) on 15th November 2003 in prov Messina, Castell'Umberto Area Ecologica, Sicily, ITALY (approx. 38.08°N, 14.8°E, altitude approximately 580 m above sea level - Google maps). The ectomycorrhizal families Pinaceae (genus Pinus) and Fagaceae (genus Quercus) were 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).
