Abstract

A new species of Cortinarius sect. Calochroi, C. lentus, is described on the basis of morphological and genetic features. It is characterised by a yellow-orange to brown-orange pileus, initially violaceous pink lamellae, a cream to pale yellow universal veil, amygdaliform to almost citriform spores, coarsely verrucose, typically narrow (Qav = 1.9) and habitat preference for chestnut woods on acidophilic soil. It is compared with the closest species from a morphological point of view, in particular with C. leochrous and C. calochrous. In order to assess its relative position within Calochroi, a phylogenetic approach based on RPB1 and ITS regions was performed. The ITS phylogenetic analysis did not resolve the position of C. lentus within sect Calochroi, but in our RPB1 phylogenetic analysis, C. sublilacinopes is closely related.
