What is Nephrodiella brevis VISCHER?

Kostikov, Igor; Hoffmann, Lucien

Abstract

Two strains were included in the protologue of the description of Nephrodiella brevis VISCHER (Xanthophyceae). The re-investigation of the two original strains shows that they represent two different taxa which belong to the genus Neocystis (Chlorophyta, Radiococcaceae). A formerly designated lectotype is shown to be in conflict with the protologue. The strain corresponding to the newly designated lectotype is combined in the genus Neocystis as N. brevis (VISCHER) KOSTIKOV et HOFFMANN, whereas the second strain is described as a new species, N. vischeri KOSTIKOV et HOFFMANN.
