Description

Collecting details

Collection 17365 was collected by V. Marinetti, det: E. Grilli (110824.03) on 24th August 2011 in Pinzolo (TN) , Trentino-Alto Adige, ITALY (approx. 46.1453°N, 10.7712°E, altitude approximately 805 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genera Alnus and Betula) and Salicaceae (genus Salix) were present.
The surrounding habitat was described as deciduous woodland with a substrate of grassy soil, 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 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). Use this webtool to explore the ecoregions visually or see a full list of current ecoregions on Wikipedia. (biome: Temperate Conifer Forests) and Koppen climate code Dfb (Cold, no dry season, warm summer).

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.
