Expanding our knowledge of Synurales (Chrysophyceae) in Florida, United States: Proposing three novel Mallomonas taxa.

ABSTRACT: We conducted a survey of Synurales diversity in Florida (United States), focusing on two established hotspots-Ocala National Forest and Myakka River State Park-and two previously unexplored sites-Manatee Lake and Lake Lee. Using transmission electron microscopy (TEM), we identified 69 species, increasing the total number recorded from Florida to 90. Among these, three species-Mallomonas cornea sp. nov., M. laureana sp. nov., and M. joergenii sp. nov.-have been newly described based on detailed morphological and molecular analyses. We have also proposed a new combination, M. poseidonii comb. et stat. nov., and established a new section, Corneae sect. nov., based on molecular phylogenetics. Our findings revealed an independent emergence of ribbed scale shield ornamentation in M. joergenii sp
