Fifty percent of the organisms were classified as "other flagellates", another 40% corresponded to the Dinophyceae class, and the remaining 7% included the Bacillariophyceae (3.3%), Ciliata (2.1%), Cianophyceae (1.4%), Dictyochophyceae (0.15%), Chlorophyceae (0.04%), and Acantharia (0.01%) (Table 1).

levieri, but if a teleomorph is formed it might belong to Venturia or
Acantharia as indicated for other Fusicladium species.
Most notably, protozoa within the subphylum Sarcomastigophora (the foraminifera, radiolaria, and
acantharia; collectively referred to as "sarcodine protozoa") exist in symbioses with a wide array of algae (Anderson, 1983; Lee and McEnery, 1983; Caron and Swanberg, 1990; Michaels, 1991).
In most biological systems, preference in general is given to [Ca.sup.2+] over [Sr.sup.2+], although a marine organism, an
Acantharia, constructs its internal skeleton of strontium sulfate [2].
