Sphaerospermopsis reniformis (Lemmermann) Zapomelová, Jezberová, Hrouzek, Hisem, Reháková and Komárková, 2010 ( Fig. 1 , Table 2)

Anabaena reniformis Lemmermann, 1898 . Sphaerospermum reniforme (Lemmermann) Zapomelová,

Jezberová, Hrouzek, Hisem, Reháková and Komárková,

2009.

Trichomes free-floating, rarely forming small clusters, irregularly screw-like coiled or circular fragments, clearly constricted at the cross-walls, not attenuated towards ends. Cells barrel-shaped to oval, sometimes slightly curved, with aerotopes, usually longer than wide, rarely isodiametric, 5.1-6.9 μm wide, 5.2-7.5 μm long. Apical cells similar to other vegetative cells, rarely a little longer, slightly curved and rounded. Heterocytes spherical or slightly elongated and barrel-shaped, solitary, intercalary, 5.9-8.7 μm wide, 6.2-9.9 μm long. Akinetes almost spherical, rarely slightly longer than wide, developing on both sides of heterocytes, solitary to 3 in row, 8.8-11.1 μm wide, 8.0-12.2 μm long.

Ecology. Planktonic in stagnant freshwater, rarely in run- ning waters ( Lemmermann, 1898), planktonic in freshwater in Korea.

Distribution. Czech Republic ( Zapomělová et al., 2009).
