Collection 10550 is Hebeloma pumilum.Description
- arrow_drop_downarrow_drop_upCollecting details
Collection 10550 was collected by A. Amman on 9th November 2004 in Pelagallinas, Guadalajara, SPAIN (41.1928°N, 3.0841°W, altitude approximately 1350 m above sea level - Google maps). The ectomycorrhizal family Pinaceae (genus Pinus) was present.
The surrounding habitat was described as coniferous, subalpine woodland with a substrate of decomposed litter, 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. 1.1: Forest – Boreal.
According to the GPS data the collection was in the Iberian conifer 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: Mediterranean Forests, Woodlands & Scrub) and Koppen climate code Cfb (Temperate, no dry season, warm summer).
