Ovate akinetes are 12-14 um in diameter and 18-20 um
long. A water bloom of this organism was reported by Cannicci (1954) in Lago
Albano (Italy), where the cyanobacteria were accompanied by Ceratium and a
bloom of rotifers. The only other mention of A.ovalisporum in nature that we
have found is a report of its presence in freshwater impoundments in Cuba by
Komarek and Kovacik (1989).
