Collection 12925 was collected by J. Vesterholt, G. Venturella (JV-03-848) on 15th November 2003 in prov Messina, Castell'Umberto, Sicily, ITALY (approx. 38.08°N, 14.8°E, altitude approximately 580 m above sea level - Google maps). The ectomycorrhizal families Cistaceae (genus Cistus) and Pinaceae (genus Pinus) were present.
The surrounding habitat was described as Mediterranean woodland, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 1.4: Forest – Temperate.
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).
