Cortinarius (Pers.) Gray (webcap toadstools)

Further Information

Characters to note in the field 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).

If there is no fresh young cap to cut in half, unless it's one of the distinctive species - forget it!
