Abstract: | Diverse collections of Cortinarius pseudofallax from several European countries were studied using morphological characters and ITS1-5.8S-ITS2 genes from sequence data. They were compared with some close species such as C. cedriolens, C. neofallax and C. parvannulatus. All these taxa share some features like a light brown pileus, a stipe provided with a more or less developed whitish veil, small and well-ornamented spores and, above all, a typical strong and perfumed acidulous smell; in addition. the phylogenetic tree built with the ITS gene sequences of these vouchers showed that they clustered in a well-supported clade, here treated as section Parvuli. Our specimens of C. pseudofallax are morphologically described and illustrated with pictures of fresh specimens and basidiospores seen under SEM. A discussion of their taxonomic relationships with another group of similar species belonging to the C. decipiens sensu lato complex is presented. |
