Inocybe vaurasii (Agaricales, Inocybaceae), a new species of the I. xanthomelas group and similar European species with asteriform spores

• Inocybe vaurasii is described as a new species belonging to Section Marginatae group Xanthomelas. A comparative mor-phological and molecular study has been carried out with other species showing basidiospores with stellate appearance and similar sizes: I. xanthomelas, I. humilis and I. subrimosa. An ITS bar code was obtained from type materials of all three of these species. The molecular analysis reveals that, despite the similarity in spore-shape, none of the species were closely related, but form distinct clades that are spread out within the Xanthomelas group. SEM photographs of the spores are pro-vided for each of the species studied. A lectotype for I. subrimosa is designated and validated and the lectotype previously designated for I. xanthomelas is here validated.
