What is "johannesbaptistia"

Johannesbaptistia is a genus of brackish–freshwater cyanobacteria which has a very characteristic morphology. It is the only member of the family Cyanothrichaceae. When the name was changed from Cyanothrix to Johannesbaptistia (due to the rules of priority in the International Code of Nomenclature for algae, fungi, and plants), the family name was not changed.
