Trachynema, a new genus in the Punctariaceae (Fucophyceae)
Two little known species of brown algae, Litosiphon mortensenii S. Lund and L. groenlandicus S. Lund, described from East Greenland have been compared with the type species of the genera Litosiphon Harv. and Asperococcus Lamour. They are distinguished from the genus Litosiphon by their basally sheat...
