Description: Zygo-/aplanospores yellow to dark yellow, oval, ellipsoid, ovoid or cylindrical-ovoid in shape, often split along its periphery, 70–75 × 40–45 µm. Surface with fine striate-rugulate pattern, smooth coating of the outer wall is occasionally present. This African green algae resembles HdV-773 reported from a late-Holocene sediment record in The Netherlands (Bakker and van Smeerdijk, 1982).

(Sub-) Fossil occurence: No information

Co-occurence: No information

Modern occurence: Species of Spirogyra have a worldwide distribution, and commonly occur in stagnant, shallow waters of mesotrophic to eutrophic small lakes and pools, or in the littoral zones of larger lakes. Many species seem to prefer rather extreme conditions, such as ephemeral standing waters, or strong daily fluctuations in pH and temperature. The sexual reproduction during which these zygospores are formed requires high temperatures, which can best be reached in shallow waters directly exposed to strong solar radiation. The optimum growth conditions for Spirogyra species lie above 20 °C (Hoshaw, 1968).
