Bandini D., Sesli E., Oertel B. & Krisai-Greilhuber I. (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 macroand
micromorphology. It is a nodulose-spored species with yellowish-ochraceous pileus colour and smooth to (sub)rimulose pileus
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.
