Cortinarius (webcap toadstools) may also be included in identification literature listed under the following higher taxa:

NBNNBN (data.nbn.org.uk) has a distribution map for Cortinarius (webcap toadstools)
BioInfoBioInfo (www.bioinfo.org.uk) has 443 host/parasite/foodplant and/or other relationships for Cortinarius (webcap toadstools)

Cortinarius is a difficult genus to identify and Telamonia are the most difficult.

Colour of young gills - cut the cap in half. (The gills always turn brown as the spores ripen so must be a young cap.)
Colour of veil on young fruitbodies. (This often disappears and always gets stained rusty by the spores, so again, must be a young fruitbody.)
Presence of blue tinges on young gills, stipe apex or flesh - cut in half (again, use a young fruitbody as the blue often fades).
Smell.
If there is no fresh young cap to cut in half, unless it’s one of the distinctive species - forget it!

cap hygrophanous (ie changes colours when imbibed with moisture)
cap non-scaly
neither cap nor stipe sticky
