(2020) Inocybe antoniniana, a new species of Inocybe section Marginatae with nodulose spores. – Sydowia 72: 95–106. Inocybe antoniniana, a new species of Inocybe section Marginatae is described in detail along with illustrations of its macro- and micromorphology. It is a nodulose-spored species with yellowish-ochraceous pileus colour and smooth to (sub)rimulose pi- leus surface, that was found up to now in Turkey, Austria and Germany. It differs from other species of the group with equally coloured pilei (e.g. I. xanthomelas, I. phaeocystidiosa or I. krieglsteineri) by smaller, often (sub)isodiametrical basidiospores, rather short and slim hymenial cystidia, and ITS sequence data. Keywords: Agaricales, Inocybaceae, Inocybe, taxonomy, molecular phylogeny. – 1 new species. Up to now the family Inocybaceae was consti- from all over the world, many of them from Asia, tuted by the genera Inocybe (Fr.: Fr.)
