Cortinariaceae

The Cortinariaceae are a large family of gilled mushrooms found worldwide, containing over 2100 species.[3] The family takes its name from its largest genus, the varied species of the genus Cortinarius. Many genera formerly in the Cortinariaceae have been placed in various other families, including Hymenogastraceae, Inocybaceae and Bolbitiaceae.

Taxonomic details

Cortinariaceae is a family of mushrooms within the Order Agaricales. The spore producing hymenium is located on the gills. The pileipellis is a cutis. The spores are brown in deposit and, in most genera in this family, the spores are ornamented.

Differences in genera

Cortinarius are mushrooms with warted spores, which are rusty-brown in deposit. Mushrooms in this genus have a partial veil which is a cortina. These mushrooms are terrestrial and mycorrhizal, and can range from small to large and fleshy.

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.

Cortinarius is one of the largest mushroom families, but due to the large amount of inedible and toxic 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.
