Collection 8898 is Hebeloma mesophaeum.Description
- arrow_drop_downarrow_drop_upCollecting details
Collection 8898 was collected by H.J. Beker on 18th October 2003 in Villers, Luxembourg, BELGIUM (approx. 50.59°N, 4.52°E, altitude approximately 110 m above sea level - Google maps). The ectomycorrhizal family Fagaceae (genus Fagus) was present.
The surrounding habitat was described as mixed 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 European Atlantic 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 Broadleaf & Mixed Forests) and Koppen climate code Cfb (Temperate, no dry season, warm summer).
