Three new species of the genus Pseudosperma (Inocybaceae).

As a result of molecular phylogenetic and morphological analyses, three new species of the genus Pseudosperma, namely P. amabile, P. amoris and P. napaeanum, are described in detail along with illustrations of their macroand micromorphology and a phylogenetic tree. In addition, to ensure a correct interpretation of the species identity in comparison with morphologically similar species, the holotype of P. flavellum, as well as an isoparatype of P. spurium and isotypes of P. aureocitrinum and P. copriniforme have been examined, and of the latter two species also an ITS sequence was obtained. A drawing of the microscopical details of all four type specimens is given.
