Taxonomy

Collection 11808 (herbarium acc. no. LY BR65-23) is Hebeloma discomorbidum. It is the epitype of heterotypic synonym Hebeloma mesophaeum var. macrosporum L. Rémy (1965) ["1964"].

Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 11808 was collected by G. Bruchet on 11th October 1965 in Lac Luitel, Isere, FRANCE (approx. 45.0881°N, 5.8497°E, altitude approximately 1300 m above sea level - Google maps). The ectomycorrhizal families Betulaceae (genus Betula) and Salicaceae (genus Salix) were present.

    The surrounding habitat was described as deciduous bog with a substrate of boggy, mossy 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. 5.4: Wetlands (inland) – Bogs, marshes, swamps, fens, peatlands.

    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.
