Recent records of telamonioid species of Cortinarius (Agaricales: Cortinariaceae) in New Brunswick, Canada

Abstract

Eight species of Cortinarius (webcaps) subgenus Telamonia and two other telamonioid Cortinarius species are reported from New Brunswick, Canada. Internal transcribed spacer sequences of these were used to build a phylogenetic tree confirming species identifications and relationships to relevant material, especially types and other Canadian collections. Descriptions and photographs of fresh material and microscopic features are provided. Habitat details, particularly potential mycorrhizal partners and dominant bryophytes, were recorded for each collection and compared with published records. Seven species, Cortinarius caninoides, Cortinarius cicindela, Cortinarius fulvescens, Cortinarius harvardensis, Cortinarius plumulosus, Cortinarius pseudobiformis, and Cortinarius valgus are new distribution records for New Brunswick, and C. plumulosus is apparently a first record for North America. Because these species have rarely been reported, they have yet to be given common names
