Silica-scaled Chrysophyceae and Synurophyceae (Chrysophyta) from Mississippi.
Silica-scaled chrysophytes are taxonomically placed in the division Chrysophyta, classes Chrysophyceae and Synurophyceae, based on ultrastructural and biochemical characteristics (Andersen 1987).
Hibberd (1976) removed prymnesiophytes from the Chrysophyceae because of differences in ultrastructure and swimming behavior.

Considering the qualitative and quantitative analyses of phytoplankton, 206 taxa distributed in nine taxonomic groups were registered: Cyanobacteria (65), Bacillariophyceae (59), Zygnemaphyceae (37), Chlorophyceae (31), Oedogoniophyceae (7), Chrysophyceae (4), Cryptophyceae (1) Chlamydophyceae (1) and Dinophyceae (1).
The influence of the five abiotic variables (orthophosphate, total phosphorus, turbidity, ammonium, and total nitrogen) on the periphyton biomass (chlorophyll 'a', ash-free dry mass, classes biovolume: Cyanophyceae, Bacillariophyceae, Chlorophyceae, Euglenophyceae, Chrysophyceae, Oedogoniophyceae) was evaluated by the Canonical Correspondence Analysis (CCA), with significance by the Monte Carlo test (p < 0.

A ordenacao das especies pela ACC sugere que a comunidade fitoplanctonica do lago do Jardim Botanico diferenciou-se dos demais lagos, principalmente por apresentar predominio de especies de Chrysophyceae (ver discussao mais abaixo) e esteve associada com elevados valores de transparencia da agua em todos os meses de estudo.
