Abstract
Schuster (1980) recognized Cephaloziella byssacea var. asperifolia (Taylor 1846) Macvicar (1912) and this variety is often recognized by later authors. However, Grolle (1983) accepted Cephaloziella divaricata (Smith & Sowerby 1800) Schiffner (1893) as the correct name for the species without mentioning any variety. Several authors have used the name Cephaloziella divaricata var. asperifolia (Taylor) Macvicar (from Eggers 1982 onwards), but Macvicar (1912) treats the variety under Cephaloziella byssacea (Roth 1800) Warnstorf (1903) and Macvicar (1926) under Cephaloziella starkei (Nees 1836) Schiffner (1900).
