Collection 13014 (herbarium acc. no. M5340, M M-0151680) is Hebeloma eburneum. It is the lectotype of heterotypic synonym Hebeloma crustuliniforme var. tiliae Bresinsky (1987).Description
- arrow_drop_downarrow_drop_upCollecting details
Collection 13014 was collected by A. Bresinsky on 4th October 1978 in Regensburg, universitatsgelande, Bavaria, GERMANY (approx. 49°N, 12.09°E, altitude approximately 370 m above sea level - Google maps). The ectomycorrhizal family Malvaceae (genus Tilia) was present.
The surrounding habitat was described as deciduous parkland 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. 14.5: Urban Areas.
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).
