Abstract

Having scoured freshwater habitats throughout Connecticut for more than two years at 151 collection sites, we have discovered the presence of eight species and one variety of the genus Vaucheria, including four species not previously known from the state: V. prona, V. taylorii, V. uncinata, and V. undulata. In addition, V. compacta, normally found in local estuaries is reported in freshwater here, and is distinguished from its local freshwater variety, V. compacta var. dulcis. Culture conditions in the laboratory stimulated production of gametangia, allowing for identification of mostly vegetative field-collected samples in their native muds. A key to the species and varieties is provided.

 


Key words: Connecticut, Vaucheria, Vaucheriaceae, Tribophyceae
