Typification of seven species of Encyonema and characterization of Encyonema leibleinii comb. nov

Abstract

The first species described in the genus Encyonema were not lectotypified. Despite the absence of types, some specialists have either defended or accepted synonymizations based on their own concepts, such as in the cases of Encyonema prostratum, Gloionema paradoxum, G. leibleinii and E. paradoxum, the type of the genus Encyonema. We aimed to lectotypify E. paradoxum, E. prostratum, E. cespitosum, E. triangulum, Gloionema paradoxum, G. leibleinii and E. lacustre. Original material was inspected and characterized. These lectotypifications resulted in the verification of the conspecificity of E. paradoxum, E. prostratum and G. leibleinii, and in the designation of E. leibleinii comb. nov. © Czech Phycological Society (2013).
