Cortinarius subgenus Vibratiles (Agaricales), a new myxacioid taxon of global scope

Abstract

A major fungal lineage of myxacioid taxa is centred around Cortinarius vibratilis. This lineage is shown by morphological and multigene molecular phylogenetic analyses of the nrDNA ITS and LSU, as well as rpb1 and rpb2 genes to form a well-supported clade, here introduced as the new subgenus C. subg. Vibratiles consisting of four sections and various small clades. Two new myxacioid sections, C. sect. Microspermi and C. sect. Turcopedes, are also proposed.
