Cortinarius evernius

Cortinarius is the largest genus of mushrooms in the world, containing an astounding number of species (often estimated well over a thousand). Although the mushrooms in Cortinarius are very diverse, it is usually pretty easy to figure out when you are looking at one, once you get the hang of it. First, they have cortinas covering their gills when young (hence the name of the genus); sometimes the tiny fibers of the cortina are ephemeral and disappear, but they frequently collapse against the stem to create a ring zone. Secondly, the spore print is rusty brown and, as a result of the rusty brown spores, the mature gills of Cortinarius mushrooms are usually also rusty brown. Finally, they are terrestrial and mycorrhizal, so you will only find them in association with trees ( http://www.mushroomexpert.com/cortinarius.html ), ( http://www.mycobank.org/MycoTaxo.aspx?Link=T&Rec=233378 )
