Mallomonas multiunca var. pocosinensis var. nov. (Synurophyceae) from freshwater localities along coastal sections of North Carolina, U.S.A.
Siver, Peter A.
A new variety of Mallomonas multiunca, M. multiunca var. pocosinensis Siver var. nov., is described from very acidic, humic waterbodies situated on the Atlantic Coastal Plain of North Carolina, U.S.A. The new variety is similar to the type in scale structure, but differs in possessing a unique type of bristle. Bristles of M. multiunca var. pocosinensis have a double cleft-like expanded distal end somewhat similar to the plume-like bristles of Mallomonas plumosa. The concave region of the distal hooked end is interrupted by the presence of a long pointed tooth that essentially divides the cleft into two sections. Based on initial findings it appears that this taxon is an important member of the phytoplankton flora in waterbodies along coastal regions of North Carolina.
