title: New Cortinarius species from Nothofagus forests in South Chile.
abstract: Four new Cortinarius species are described from Nothofagus forests in South Chile. Cortinarius aurantiorufus and C. punctatisporus, subgenus Phlegmacium, stirps Inflatipes, are mainly characterized by a viscid to glutinous pileus and a bulbous whitish stipe. They differ in the color of the pileus, and shape, ornamentation, and size of the basidiospores. Futhermore, C. punctatisporus has a translucently striate pileus. Cortinarius rubrivelatus and C. parahumilis belong to subgenus Telamonia, stirps Brunneivelatus and Scabrisporus, respectively. Cortinarius rubrivelatus has a reddish veil, a viscid pileus, and large, ellipsoid to amygdaliform basidiospores. Cortinarius parahumilis has small, subglobose to broadly elliptical, minutely verrucose basidiospores and a viscid pileus.
