The Leaf Chronicle is reporting that Didymo algae (Didymosphenia geminata) has been found east of the Mississippi River for the first time. Scientists for the Tennessee Valley Authority say there are thick mats of it in the Tennessee River, and no one's sure how it got there. No one's quite sure where it's from either: the species is been noted as being invasive in New Zealand, native in Canada, status uncertain in the U.S.

Didymo was prior to this week (28 Sept. 2005) only known from New Zealand in Southland's lower Waiau and the Makarora River. This week, it has been confirmed in the Buller River (West Coast) and the Hawea River in Otago, New Zealand's largest river system.
