Cortinarius is a genus of mushrooms. It is suspected to be the largest genus of agarics, containing over a thousand different species. A common feature among all species in the genus Cortinarius is that young specimens have a cortina (veil) between the cap and the stem, hence the name. This veil protects the gills in younger specimens and usually disappears leaving little to no trace of itself as the mushroom grows. The spores of a Cortinarius mushroom are rusty brown to brownish red in color. It is usually possible to identify a mushroom as being a member of the genus, but extremely difficult to positively identify the species as many of the species are nearly identical. All mushrooms in this genus form mycorrhizae. Image File history File links Cortinarius_rubellus_01. ...

Several mushrooms in the genus Cortinarius are poisonous. Some are even lethal, such as Cortinarius rubellus and Cortinarius orellanus. Therefore, a common rule when it comes to mushrooms from this genus are that none of them should be eaten or even tasted. It should be noted, however, that some species - notably the giant of the genus, Cortinarius praestans - are edible and appreciated in several European countries.
