For plant associations you can restrict to choosing collections where a particular genus or family was noted by the collector as being present. Enable the checkbox to further restrict to those collections where only that genus or family (and no other) was recorded. This restriction increases the likelihood that the Hebeloma and the plant are in a mycorrhizal associationA mycorrhizal relationship between a fungus and a plant is symbiotic relationship where each species is providing something to the other. In a mycorrhizal relationship the fungus has integrated into the plant's root system; providing a means for the two species to exchange water, sugars and other nutrients with each other rather than being coincidentally co-located.

There are four ways of restricting to a particular habitat choosing a habitat. You can select none, one or more of these and collections meeting all the selected criteria will be shown.

– The first selection box uses keywords from the collector's description of the locality and habitat as recorded on the collecting sheet or label.

<Any> alpine arctic base-poor base-rich bog or boggy boreal burnt ground cadaveric coniferous woodland deciduous woodland dune farmland fenland grassland heathland maquis mixed woodland pine barrens plantation pondside, streamside, lakeside, riverside roadside, pathside, campsite, car park (non urban) sandy ground shrubland slagheap subalpine subtropical tropical tropical or subtropical highland tundra urban with Sphagnum or deeply-mossy woodland

– By using the International Union for Conservation of Nature (IUCN)'s definition of the habitat. This habitat is estimated by mapping habitat and substrate collection information, as recorded by the collector, to an IUCN habitat using a standardised set of rules. Please see this page for a full list of IUCN habitats.

– By using the World Wildlife Fund's (WWF) division of the world into terrestrial ecoregions. The ecoregion 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. Be aware that this division of the world into ecoregions is relatively coarse and does not take into account microhabitats, so for example the alpine regions in Europe would be mapped into an ecoregion of temperate conifer forests, although the area above the treeline is clearly a rather different habitat.

– Finally, by using WWF biomes rather than ecoregion. Biomes are a more coarse-grained division than ecoregion. Again GPS data is used to determine the biome for the collection and so it is important to be aware that this is a rather coarse mapping into biomes.
