Taxonomy
Collection 1000243 (herbarium acc. no. PRC B78a) is Hebeloma sacchariolens. It is the lectotype of heterotypic synonym Hebeloma odoratum Velen. (1920).Note: The material in a bottle of in alcohol/formaldehyde is labelled as Mnichovice 1918 and hence is very likely to be original material and hence suitable as lectotype.
Description
- arrow_drop_downarrow_drop_upCollecting details
Collection 1000243 was collected by J. Velenovsky in 1918 in Mnichovice, CZECH REPUBLIC (49.5612°N, 14.4245°E, altitude approximately 590 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as 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 Western European broadleaf 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).
