THE FIRST OCCURRENCE OF THE CHRYSOPHYTE ALGA AMPHIRHIZA EPIZOOTIC A FROM NORTH AMERICA

摘要

There are numerous genera of golden-brown algae (Chrysophyta, Chryso-phyceae) living in freshwater habitats. Reports of their distribution had been scattered throughout the algal literature for a long time, but only recently have these been summarized for North America (Nicholls Wujek 2003). This paper reports the occurrence of the chrysophycean alga Amphirhiza epizootica Skuja in Michigan, a species first described from Sweden (Skuja 1948).
