Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 13682 was collected by G. Manavella on 6th October 2010 in Zona di Mondavi - Commune de Ceva, localité Poggi San Siro, Piedmont, ITALY (approx. 44.363°N, 8.0011°E, altitude approximately 500 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Quercus) was present.

    The surrounding habitat was described as not recorded with a substrate of calcareous soil.

    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).

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.
