Wollea Bornet & Flahault (1886: 223)
Type: W. saccata Bornet & Flahault (1886: 233)
Filamentous, colonial; colonies macroscopic, gelatinous, smooth, irregularly cylindrical or subspherical, sometimes tube-like. Trichomes the same width along the entire length, straight or slightly curved, uniseriate, unbranched, not attenuated or widened at the ends, deeply constricted at the cross walls; apical cells rounded; irregular to parallelly and densely arranged in common, diffluent mucilage. Heterocytes intercalary, solitary. Akinetes arise paraheterocytically, either side of the heterocytes, in short series, spherical or oval. Vegetative cells divide crosswise by binary fission. Reproduction by production of hormogonia.
A genus of nine species known from freshwater lakes and reservoirs, rivers and estuaries. Here three species are described from north-eastern Australia. Bibliography: Desikachary (1959), Komárek (2013), Komárek et al. (2014), Kozlíková-Zapomělová et al. (2016).
