Orellani (Cortinarius sect. orellani)
The Orellani are a group of seven related species in the genus Cortinarius that have been classified as a section of the subgenus Leprocybe or a subgenus in their own right. They are among world’s most poisonous mushrooms as they contain the highly toxic compound orellanine. The best-known species are the deadly webcap (Cortinarius rubellus, formerly also known as C. speciosissimus or C. orellanoides) and the fool’s webcap, C. orellanus.
