Abstract

Abstract : The discovery of exsiccata no 632 of De Notaris's Erbario Crittogamico Italiano now provides a lectotype for Sellaphora nigri (De Notaris) C.E. Wetzel & Ector, a common and widely distributed freshwater species originally described from the River Po (Italy). The lectotype takes precedence over the neotype previously designated by Wetzel and co-authors. New observations were made using light and scanning electron microscopy. A few notes on diatoms described in Erbario Crittogamico Italiano are briefly presented, along with illustrations of species present in the original protologue, including Nitzschia amphibia var. padana De Notaris nomen nudum .
