Taxonomic details
Cortinariaceae is a family of mushrooms within the Order Agaricales
The fungal order Agaricales, also known as gilled mushrooms (for their distinctive gills) or euagarics, contains some of the most familiar types of mushrooms. The order has 33 extant families, 413 genera, and over 13,000 described species, a ...

Edibility
Despite the vast number of species in Cortinariaceae, this group is not widely eaten, and is generally avoided. There are many toxic species in this group and few are highly prized.

species, most authors recommend not eating any ''Cortinarius''. At one point, the Polish ate the fool's webcap, '' Cortinarius orellanus'', until people began to get poisoned from eating the mushroom. It is now known that several ''Cortinarius'' species contain a deadly toxin, orellanine, which causes kidney failure. Most ''Cortinarius'' are either too small or unpleasant-tasting to eat, but some, such as the gypsy mushroom ('' Cortinarius caperatus'') and the large and tasty '' Cortinarius praestans'', are highly esteemed. However, some mycologists believe that no ''Cortinarius'' should be eaten.
